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






2. 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.






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






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






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






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






7. Always 10 for scientific notation






8. An integer that is found by squaring another integer. You already know how to find the square root of 25 because it is a perfect square: 5 x 5 = 25 - or you could write it as 52 = 25. So 25 is a perfect square - and its square root is 5.






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






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






11. Scientific notation requires there to be only






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






13. 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.






14. The cube root of zero is






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






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






17. The decimal part






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






19. To add or subtract numbers written with exponents:






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






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






22. 0^5 =






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






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. 1^4 =






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






27. The square root of zero is






28. To add powers of ten:






29. To subtract powers of ten:






30. 3^0 =






31. 10 - or 1 with the decimal point moved one place to the right






32. To divide powers of 10:






33. To divide powers that have the same base:






34. To divide powers of ten:






35. = 0.01 - or 1 with the decimal point moved two places to the left.






36. 0 to any power is equal to






37. Valid powers of 10 for engineering notation are:






38. Multiplying by 10






39. Valid powers-of-10 for engineering notation






40. To multiply powers of ten:






41. Any number with a negative exponent is equal to






42. The cube root of a negative number is also a






43. 5^1 =






44. 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.






45. Dividing by 10






46. Indicates the number to be multiplied.






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






48. Indicates the number of times the base is to be multiplied.






49.






50. 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
