7.1 Dividing fractions
To divide fractions, write the divison as multiplication by the reciprocal of the divisor :
8281 212 8281 53 ———— ÷ ——— = ———— • ——— 12 53 12 212
Multiplying exponents :
7.2 22 multiplied by 212 = 2(2 + 12) = 214
Equation at the end of step 7 :
(72•132•53) 28 ——————————— ÷ 2 • —— (214•3) 5
Step 8 :
(72•132•53) Divide ——————————— by 2 (214•3)
Multiplying exponents :
8.1 214 multiplied by 21 = 2(14 + 1) = 215
Equation at the end of step 8 :
(72•132•53) 28 ——————————— • —— (215•3) 5
Step 9 :
Multiplying exponents :
9.1 72 multiplied by 71 = 7(2 + 1) = 73
Dividing exponents :
9.2 53 divided by 51 = 5(3 - 1) = 52
Dividing exponents :
9.3 22 divided by 215 = 2(2 - 15) = 2(-13) = 1/213
Final result :
(73•132•52) ——————————— = 58.96708 (213•3)
