Answer: So for us to solve the expression g5h³, we first substitute the given values of g and h.
Given that g = 2 and h = 7, we can substitute these values into the expression.
So, g5h³ becomes 2 × 5 × 7³.
Next, we perform the calculations according to the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
In this case, there are no parentheses or exponents, so we move on to the multiplication step.
Multiplying 2 by 5 gives us 10, and then multiplying that result by 7³ gives us the final answer.
Calculating 7³, we get 343.
So, the expression g5h³, when g = 2 and h = 7, equals 10 × 343, which is 3430.
Therefore, the final answer is 3430.
