SOLUTION: I need to check and see if I got the right answer 1/5{1/2{3(s+7)^2/3]}40 I did not know how to write over 3, so I also tried to explain it here 1/5 { 1/2 [3(s+7)squared over

Question 222092: I need to check and see if I got the right answer

NO! You went TOO FAR, and you broke the LAW of MATH!!

You can multiply 1/5*1/2*3*40--these are all numbers in a product, and the result is 1/10*3*40 = 1/10*120= 12. HOWEVER, when it comes to multiplying times (s+7)^2/3, the Distributive Property does NOT apply because of the exponent 2/3. The final answer is 12(s+7)^2/3. You can't go any farther with this!!
