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. 1 to any power is equal to






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






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






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






5. To find the cube root of any number - simply key in the number (the radicand) and press cube-root key. On most calculators - the cube-root function is a 2nd level function. This means you have to press the 2nd key before pressing the key for the






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






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






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






9. 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






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






11. To divide powers of 10:






12. To divide powers that have the same base:






13. 100 - or 1 with the decimal point moved two places to the right






14. 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.






15. Dividing by 10






16. 10 - or 1 with the decimal point moved one place to the right






17. When the exponents are not the same






18. To add powers of ten:






19. = 0.01 - or 1 with the decimal point moved two places to the left.






20. 1 to any power is equal to






21. The square root of 9 is






22. 0 to any power is equal to






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






24.






25. = 0.1 - or 1 with the decimal point moved one place to the left.






26. Step 1: Add the exponents Step 2: Use the common base






27. 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.






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






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






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






31. 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






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






33. 0^5 =






34. The cube root of zero is






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






36. 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






37. To divide powers of ten:






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






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






40. Numbers with exponents can be directly multiplied or divided only when they have the






41. The square of 3 is






42. 3^0 =






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






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






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






46. Indicates the number to be multiplied.






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






48. To multiply powers of 10:






49. Multiplying by 10






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