Final answer:
The expression (-3)(-3)(-3)(-3)(-3)(-3) can be written as (-3)^6.
Step-by-step explanation:
To write the expression using exponents, we need to cube the digit term (-3) and multiply the exponent of the exponential term (1) by 3.
The expression (-3)(-3)(-3)(-3)(-3)(-3) can be written as (-3)^6.
Therefore, the correct answer is D) (–3)^6.
