We are given the following expression:
[tex]8.\mleft(2+3\mright)^2-4^2[/tex]To solve the expression we will add the numbers inside the parenthesis:
[tex]8.(2+3)^2-4^2=8(5^2)-4^2[/tex]Now we solve the squares:
[tex]8(5^2)-4^2=8(25)-16[/tex]Now we solve the product:
[tex]8(25)-16=200-16[/tex]Now we solve the operation:
[tex]200-16=184[/tex]Therefore, the expression is equivalent to 184.
