Answer:
The answer is D
Step-by-step explanation:
When you have an exponent on a number it just means that number must be multiplied by itself as many times as the exponent says.
Example: 6^2 this just means 6*6 since the exponent is 2.
Now for this question since the exponent is 4 you get your expression 6^4 or 6*6*6*6.
Hope this helped.
