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. Valid powers-of-10 for engineering notation






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






3. The square root of zero is






4. Any number with a negative exponent is equal to






5. 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






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






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






8. 3^0 =






9. The decimal part






10. 1^4 =






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






12. 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






13. To divide powers of 10:






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






15. 0 to any power is equal to






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






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






18. 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






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






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






21. Always 10 for scientific notation






22. For the 10






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






24. The square root of 9 is






25. 10 - or 1 with the decimal point moved one place to the right






26. To divide powers of ten:






27. To multiply powers of ten:






28. = 0.1 - or 1 with the decimal point moved one place to the left.






29. 1 to any power is equal to






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 moving the decimal point to the right (multiplying by 10)






32. Valid powers of 10 for engineering notation are:






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






34. 0^5 =






35. 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.






36. To multiply powers of 10:






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






38. The cube root of zero is






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






40. 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






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






42. The square of 3 is






43. Dividing by 10






44. Indicates the number to be multiplied.






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






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