Answer:
D, (7 x 7 x 7 x 7 x 7) / (7 x 7)
Explanation:
Look at the numerator of the fraction. You will see 7^5, or 7 to the 5th power. This means you must multiply 7 by itself 4 times, to get yourself the numerator of 7 x 7 x 7 x 7 x 7. This means your choices are B (or the second option from the top) or D (or the last option from the top).
However, take note that your original equation is a fraction, meaning you would divide, and not multiply. This means B, or the second option, is incorrect, because they are multiplying in that expression, when a fraction means to divide.
Your only other option is D, where they have portrayed both 7 to the fifth correctly in the numerator, and then 7 squared in the denominator.
