$52$

PEMDAS is Parentheses - Exponents - Multiplication/Division - Addition/Subtraction.

First, you would do exponents, since there are no parentheses. $4^2$ is $16$ . Next, you would do Multiplication/Division.

$3*16=48$

Next, you would do Addition/Subtraction,

$48+5-1=52$

So

$4^2=16$

$3*16=48$

$48+5-1=52$
