Question

Evaluate this exponential expression.8.(2+ 3)^2 – 4^2

Answer 1

We are given the following expression:

`8.\mleft(2+3\mright)^2-4^2`

To solve the expression we will add the numbers inside the parenthesis:

`8.(2+3)^2-4^2=8(5^2)-4^2`

Now we solve the squares:

`8(5^2)-4^2=8(25)-16`

Now we solve the product:

`8(25)-16=200-16`

Now we solve the operation:

`200-16=184`

Therefore, the expression is equivalent to 184.
