Question

Use your calculator to evaluate the expression below. Round your answer to the nearest thousandth.

-2.15(7.37-7.97)²

Answer 1

-0.774

Explanation:

When you follow PEMDAS, the first thing to do is parenthesis. When (7.37-7.97) is calculated, it equals -.6. Then, you're going to square that, which is 0.36. Finally, multiply 0.36 x -2.15, which is -0.774. Since this answer is already rounded to the nearest thousandth, there's no need for rounding.

Hope this helps!
