Answer:
(9+9+7^2)-4+9= 72
Step-by-step explanation:
Using PEMDAS, we can solve this problem easily. First, look for parentheses. Inside of the parentheses is an exponent, 7^2. This equals 49. Continuing to solve inside the parentheses, we get 9+9+49= 67. Now, we add and subtract from left to right. Our new equation looks like 67-4+9=?. 67 minus 4 is 63, and 63 plus 9 is 72. Thus, the answer to this equation is 72.
Hope this helps!
