The left side isn't clear with two equal signs. Therefore, I will give two possible answers.
If it is 8 x (14 x 7)=14 x (8 x 7), that is the associative property of multiplication.
They may have wanted the product, which is 784.
If it is 8 x (14+7)=? + (8 x 7), then it should be (8 x 14)+ (8 x 7), which is the distributive property of multiplication. There, the 8 is multiplied by each of the terms in the parentheses and the two products are added. That answer is 112+56=168, which is 8 x 21.
