CLEP General Mathematics: Powers Exponents And Roots

Subjects : clep, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Increase the value of the exponent by 1 (multiplying by 10)






2. When you increase the value of the power-of-10 exponent






3. 0^5 =






4. When working with powers of ten and scientific notation it is often necessary to adjust the position of the decimal point in the coefficient or to change the value of the exponent. When changing one of these terms - it is important that






5. To divide powers that have the same base:






6. To find the square root of any number - simply key in the number (the radicand) and press the






7. To multiply powers of ten:






8. 1 to any power is equal to






9. The symbol for the cube root of a number is






10. Dividing by 10






11. When you move the decimal point in the coefficient to the left






12. When the exponents are not the same






13. A very large number such as 2 -000 -000 -000 can be written with scientific notation as






14. To add or subtract numbers written with exponents:






15. Valid powers-of-10 for engineering notation






16. Any number with an exponent of 1 is equal to






17. Negative cube roots are okay ... negative square roots are






18. When you change the position of the decimal point in a coefficient value






19. Adding and subtracting powers of ten can be a bit more complicated than multiplying and dividing. The main problem is that powers of ten can be added or subtracted only when both terms have the






20. 1^4 =






21. A very small number such as 0.000000674 can be written with scientific notation as






22. Powers of ten can be added or subtracted only when their exponents






23. When working with scientific notation - you are often required to change the location of the decimal point in the coefficient - but when you move the decimal point - you must






24. Is a special form of power-of-10 notation where the exponents for the 10s must be 0 or multiples of 3. There must be 1 - 2 - or 3 digits on the left side of the decimal point.






25. There are no special rules for adding and subtracting numbers that are written with exponents.






26. Don't bother trying to find the square root of a negative number.






27. To divide powers that have the same base; what do you do to the divisor from the exponent of the dividend?






28. Indicates the number to be multiplied.






29. Represents 1 preceded by 17 zeros and a decimal point.






30. When this is exactly one digit (not including zero) to the left of the decimal point. This sometimes called the normalized form.






31. To subtract powers of ten:






32. 10^-1 = 0.1 - or 1 with the decimal point moved one place to the left. 10^-2 = 0.01 - or 1 with the decimal point moved two places to the left. 10^-18 represents 1 preceded by 17 zeros and a decimal point.






33. 100 - or 1 with the decimal point moved two places to the right






34. Allows you to express very large and very small numbers without using large numbers of digits and decimal places. It's all done with powers of ten.






35. To multiply or divide exponent terms that do not have the same base:






36. Any number with an exponent of 0 is equal to






37. Any number with a negative exponent is equal to






38.






39. To add powers of ten:






40. Because the exponent for the base-10 must be 0 or a multiple of 3 - the coefficient cannot always be a value between -9 and 9. Instead - the coefficients for engineering notation will be between






41. A negative exponent does not mean the decimal value is negative. It means the decimal value is






42. What number multiplied by itself is equal to 16? The answer is 4. Why?






43. The decimal part






44. Multiplying by 10






45. 1 to any power is equal to






46. When moving the decimal point to the right (multiplying by 10)






47. A number with an exponent of 3 is often said to be






48. For the 10






49. What number multiplied by itself is equal to 4? Well - 2. x 2 = 4 - so the answer is






50. = 0.01 - or 1 with the decimal point moved two places to the left.
