Answer below....

Step-by-step explanation:

so first you start with the parentheses as you do in the order of operations. So you add them up which is 5. Then move to exponents which is the 2 that is higher than the actual numbers. which you do 5x5 which is 25. After then you multiply 3x25 which is 75. Then you  multiply 2x75 which equals 150. then you add 7 then voila. your answer is 157. hope this helped.
