Answer
-11
Work Step by Step
$25-[(3-5)+(14-18)]^{2}$
To simplify this expression, first perform the operations in parentheses.
$25-[-2+(-4)]^{2}=25-[-(2+4)]^{2}=25-[-6]^{2}$
Next, perform the exponent on the number in brackets.
$25-(-6\times-6)=25-36$
Finally, perform the remaining operation.
$25-36=25+(-36)=-11$
