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. To divide powers that have the same base:






2. 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






3. 3^0 =






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






5. 1 to any power is equal to






6. 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






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






8. To multiply powers of ten:






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






10. 5^1 =






11. 100 - or 1 with the decimal point moved two places to the right






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






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






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






15. Any number with a negative exponent is equal to






16. Always 10 for scientific notation






17. Indicates the number to be multiplied.






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






19. 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.






20. To subtract powers of ten:






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






22. Valid powers of 10 for engineering notation are:






23. Multiplying by 10






24. To add or subtract numbers written with exponents:






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






26. Scientific notation requires there to be only






27. = 0.01 - or 1 with the decimal point moved two places to the left.






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






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






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






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






33. The square root of zero is






34. For the 10






35. 0^5 =






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






37. 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.






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






39. 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.






40. Dividing by 10






41. 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.






42. The cube root of zero is






43.






44. To divide powers of ten:






45. 0 to any power is equal to






46. To add powers of ten:






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






48. Valid powers-of-10 for engineering notation






49. 1 to any power is equal to






50. When the exponents are not the same
