| Here is a practice quiz to help you with problems in math. The answers are provided at the bottom of the page with a breif description of how to work the problem. --------------------------------------------------------- * = an exponent of 2 ^ = an exponent of 3 ` = an exponent of 4 ' = an exponent of 5 Find the degree of the polynomial. 1. n - 2p* 2. 4xy + 9x^z* + 17rs^ 3. 3ab^ - 5a*b* + 4ab Find the sum or difference. 4. (2x* - 5x + 7)-(3x^ + x* + 2) 5. (11m*n* + 4mn - 6)+(5m*n* - 6mn + 17) Express each number in scientific notation. 6. 240,000 7. 4,880,000,000 8. 796 x 10^ Find each product. 9. 4ab(3a* - 7b*) 10. 4x*y(2x^ - 3x*y* + y`) ********ANSWERS******** 1. 2 2. 5 3. 4 To find the degree of a polynomial, add the exponents up and then find the sum. That is your degree. ------------------------------------------- 4. -3x^ + x* - 5x + 5 5. 16m*n* - 2mn + 11 Add or subtract SIMILAR terms. ------------------------------ 6. 2.4 x 10' 7. 4.88 x 10 to the 9th 8. 7.96 x 10' Take the number and put a decimal in between the FIRST two numbers. Count how many digits you need to go over to reach to end of the original number. ------------------------------ 9. 12a^b - 28ab^ 10. 8x'y - 12x`y^ + 4x*y' Simply use the distributive property. remember to add of subtract SIMILAR terms! I hope this site helped you out!!!!!!!!!!!!!!!!!!!!!!!!!!! |
