36ab3(3 to third power)bc2(2 to 2nd power) over 24ab(4 power)c(2 power) I can't be sure from the above, but I think your problem might be this: 36(ab3)3(bc2)2 --------------- 24(ab)4c2 If so then first make sure every factor inside parentheses has an exponent showing even if it is 1. 36(a1b3)3(b1c2)2 ---------------- 24(a1b1)4c2 Now remove parentheses by multiplying every inner exponent by the outer exponents: 36a3b9b2c4 ------------ 24a4b4c2 Add the exponents of the b's on top 36a3b11c4 ------------ 24a4b4c2 Divide the 36 and the 24 both by 12 3a3b11c4 ----------- 2a4b4c2 Subtract the exponents of the a's (larger minus smaller, 4-3), placing the result a1 in the denominator, because the denominator contains the larger exponent 4: 3b11c4 --------- 2a1b4c2 3b11c4 --------- 2a1b4c2 Subtract the exponents of the b's (larger minus smaller, 11-4), placing the result b7 in the numerator, because the numerator contains the larger exponent 11: 3b7c4 -------- 2a1c2 Subtract the exponents of the c's (larger minus smaller, 4-2), placing the result c2 in the numerator, because the numerator contains the larger exponent 4: 3b7c2 -------- 2a1 Now you can eliminate the 1 exponent of a in the denominator 3b7c2 ------- 2a Edwin AnlytcPhil@aol.com
