1. 8^3 * 8^2, 8^5, and (2^3)^5
2. 6^9, and 6^5 x 6^4
Simplifying the given expression, it is found that Curtis is correct.
<h3>How to simplify the expression?</h3>
The expression to be simplified is given by:
[4(10) - 3²] + 6(4)
The non-related operations can be solved first, hence:
[4(10) - 3²] + 6(4) = [40 - 9] + 24
For the square, we have to consider that:
- For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².
- For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².
The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:
[40 - 9] + 24 = 31 + 24 = 55.
Which means that Curtis is correct.

Answer:
9/35
Step-by-step explanation:
Let x be the total trip distance.
Since Maria is assigned to drive 3/7 of the total trip, she is to drive 3x/7.
Now, since Maria has driven 3/5 of 3x/7, the amount of the total trip she has driven is 3/5 × 3x/7 = 9x/35.
So, Maria has driven 9/35 of the total trip.
Problem 1: -5^2 + 10^2
Work:
-5^2 + 10^2—> (-5 x -5) + (10 x 10) —> 25 + 100 = 125
Answer:
125
Problem 2: (2 x (-5) x 3) + 3^3
Work:
(2 x (-5) x 3) + 3^3 > (-25 x 3) + 3^3 —> -75 + 3^3 —> -75 + 27 —> 48
Answer:
48
