-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. $25-36=25+(-36)=-11$
