Answer:
8 1/2
Explanation:
Given:
- m = 2 1/2
- n = 4 1/4
- m^2 + (n - 2)
Looks like you already know what PEMDAS is.
Substitute the values of m and n into the underlined equation-- make sure you include parentheses around the numbers you substitute as this helps you easily see what you are doing.
(2 1/2)^2 + ((4 1/4) - 2)
Start inside the parentheses and subtract 2 from 4 1/4, then rewrite your equation.
(2 1/2)^2 + (2 1/4)
Next evaluate the exponent.
(6 1/4) + (2 1/4)
Since the fractions already have common denominators, you can add the whole numbers and the fractions together.
8 2/4
2/4 can be simplified by dividing both sides by 2/2.
8 1/2 is the final, fully simplified answer.
