You must use the order of operations, PEMDAS.

Innermost parentheses first.

$4 (30 - {(3 + 1)}^{2})$ $4(30-(3+1)^2)$

$4 (30 - {(4)}^{2})$ $4(30-(4)^2)$

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

$4 (30 - 16)$ $4(30-16)$

Continue inside the parentheses but now target the subtraction

$4 (14)$ $4(14)$

This last step is implied multiplication

$56$ $56$
