It depends on the answer. The parenthesis' placement can change the answer to the problem.
(3x3+1)2+1=7x2+1=15 and that is how you use parenthesis but, always do parenthesis before you do anything else......^_^
No, it is not. To be correct, the expression requires parenthesis, which are missing.
the equation is 5(a+2) if a is 1 than the answer is 15 if a is 2 than the answer is 20 if a is 3 than the answer is 25 etc...
