Answer:

(7+6) x (4+5)

Explanation:

Since both 7+6 and 4+5 are being added, the parenthesis around them shows that. Parenthesis come first in solving equations, so the steps would look like:

(7+6) x (4+5)

13 x 9

177

In any other equation, the wrong numbers would be multiplied. Like option 3, what would happen would be:

7+(6x4)+5

7+24+5

36
