$52$ $52$

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

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

$3 \cdot 16 = 48$ $3*16=48$

Next, you would do Addition/Subtraction,

$48 + 5 - 1 = 52$ $48+5-1=52$

So

$4^{2} = 16$ $4^2=16$

$3 \cdot 16 = 48$ $3*16=48$

$48 + 5 - 1 = 52$ $48+5-1=52$
