3x3x3x3 = 81
x.x.x.x = x^4
2x2x2x2 = 16
B. 81x^4/16
Let's find x. This will allow us to find the value of the second expression.
x - 3 = 1
x = 4
Now, we can simply plug this x-value into the second expression to obtain 4^2 - 3(4) - 1 = 3.
Thus, our answer is 3.

Answer:
3x^5 . 7x^9
3.7.x^5 .x^9
If base is equal when at multiplication we add index
21.x^(5+9)
21 . x^(14)
