924

Explanation:

[(ab)×c]2×d,a=25,b=14,c=3,d=7

To evaluate, we need to replace the letters with numbers and then perform the operation.

First, we have to subtract a from b. This will give us 11.

[(2514)×3]2×14=(11×3)2×14

Then we must perform the multiplications. It doesn't matter which order we perform these in, as multiplication is commutative (a×b×c=a×c×b=c×b×a).

11×3×2×14=924
