Final answer:
The exponential form of (-3/4)(-3/4)(-3/4) is (-3/4)³, because -3/4 is multiplied by itself three times.
Step-by-step explanation:
The expression (-3/4)(-3/4)(-3/4) can be written in exponential form by identifying the base, which is -3/4, and counting how many times it is multiplied by itself. Since -3/4 is being multiplied by itself three times, the expression in exponential form is (-3/4)³. Therefore, the correct answer is a) (-3/4)³.
Exponential form simplifies the process of writing multiplications of the same number by using an exponent to denote how many times the base is multiplied by itself. In this case, since there are three occurrences of -3/4, the exponent is 3.
