Final answer:
To solve the expression |m²+n²| with given values m=-5 and n=3, we square each variable, add the results, and then apply the absolute value to get the final answer, which is 34.
Step-by-step explanation:
The question is asking us to evaluate the expression |m²+n²| when m=-5 and n=3. To solve this, we first need to substitute the values of m and n into the expression.
First, calculate m²: (-5)² = 25.
Next, calculate n²: (3)² = 9.
Now, add these two results to find the value of the expression: 25 + 9 = 34.
Since the expression involves an absolute value, |34|, and 34 is positive, the expression remains 34.
Therefore, the value of the expression when m = -5 and n = 3 is 34.
