Answer 1

Answer:

22

Step-by-step explanation:

Plugging in the numbers:

(-5)^2 - 3

$\huge \green{ \bold{Given: }}$

$\bold \blue {n = - 5} \\ \bold \blue{m = 3}$

$\huge \orange{ \bold {Solution:}}$

$\bold \red{ {n}^{2} - m} \\ \bold { = {( - 5)}^{2} - 3 } \\ \bold { = 25 - 3} \\ \bold{ = \underline{22}}$
