Answer:
The value of the given expression is 28.
The given expression is |m² - 7| + n², m = -2 and n = 5.
We need to find the value of the expression with the given m and n values.
What is an expression?
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Now, substitute m = -2 and n = 5 in the given expression and simplify.
That is, |(-2)² - 7| + 5²
=|4-7|+25
=|-3|+25
=3+25
=28
Therefore, the value of the given expression is 28.
