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. For the 10






2. 1 to any power is equal to






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

8. The square root of 9 is






9. To add or subtract numbers written with exponents:






10. Multiplying by 10






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






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






13. The square of 3 is






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






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






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






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






18. 5^1 =






19. 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






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






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






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






23. 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






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






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






26. To subtract powers of ten:






27. 100 - or 1 with the decimal point moved two places to the right






28. To add powers of ten:






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






30. 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.






31. 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






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






33. 1 to any power is equal to






34. Valid powers-of-10 for engineering notation






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






36. When the exponents are not the same






37.






38. 0 to any power is equal to






39. The cube root of zero is






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






41. Valid powers of 10 for engineering notation are:






42. 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
