Both claims are false. In fact, 
and 
are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that
So, it doesn't matter if is positive or negative: the multiplication of one number and its inverse will always be 1: for example,
Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:
So, the multiplication of two negative numbers is a positive number.
When you multiply powers, you add them. You keep the constant (2) the same.
3+18= 21
2^21 <=== the answer
“D” is the answer.
I hope this helps!
