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






2. 1 to any power is equal to






3. 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.






4. A number is a second number which - when multiplied by itself three times - equals the original number.






5. 100 - or 1 with the decimal point moved two places to the right






6. 0 to any power is equal to






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






8. 10 - or 1 with the decimal point moved one place to the right






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






10. Any number with a negative exponent is equal to






11. Scientific notation requires there to be only






12. 5^1 =






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






14. 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






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






16. 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






17. To divide powers of ten:






18. The square of 3 is






19. To divide powers that have the same base:






20. Valid powers-of-10 for engineering notation






21. The symbol for the square root of a number is the - a sign placed in front of an expression to denote that a root is to be extracted.






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






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






24. 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






25. To multiply powers of ten:






26. A number with an exponent of 2 is often said to be






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






28. Indicates the number to be multiplied.






29. The square root of 9 is






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






31. The decimal part






32. A number - when multiplied by itself - is equal to a given number.






33. To add powers of ten:






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






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






36. Dividing by 10






37. 3^0 =






38.






39. Multiplying by 10






40. When you decrease the value of the power-of-10 exponent






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






42. To multiply powers of 10:






43. Increase the value of the exponent by 1 (multiplying by 10)






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






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






46. 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






47. 1^4 =






48. 0^5 =






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