You must use the order of operations, PEMDAS.

Innermost parentheses first.

#4(30-(3+1)^2)#

#4(30-(4)^2)#

Continue to working inside the parentheses but now target the exponents.

#4(30-16)#

Continue inside the parentheses but now target the subtraction

#4(14)#

This last step is implied multiplication

#56#
