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






2. For the 10






3. The square root of zero is






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






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






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






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






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






9. The cube root of zero is






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






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






12. 0 to any power is equal to






13. 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.






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






15. Multiplying by 10






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






17. To divide powers of 10:






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






19. Dividing by 10






20. 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






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






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






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






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






25. To add powers of ten:






26. To divide powers that have the same base:






27. Always 10 for scientific notation






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






29. Indicates the number to be multiplied.






30. 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






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






32. 1^4 =






33. To divide powers of ten:






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






35. The square root of 9 is






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






37. 1 to any power is equal to






38. 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.






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






40. 1 to any power is equal to






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






42. The decimal part






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






44. Valid powers-of-10 for engineering notation






45. To subtract powers of ten:






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






47. When you move the decimal point in the coefficient to the right






48. Scientific notation requires there to be only






49. 5^1 =






50. 3^0 =
