The first step to evaluate the expression 7^3 - 4 * 3 + 8 is to determine the order of operations. The order of operations states that calculations should be performed in a specific order: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
In this expression, there are no parentheses, so we move on to the next step: exponents.
The expression 7^3 means raising 7 to the power of 3, which is equal to 7 * 7 * 7 = 343.
So, the first step to evaluate this expression is to calculate the exponent.
Therefore, the correct answer is A. Exponent.
Wouldn't It Be Exponents First, For This Expression In Particular?
