Question

The expression (3z2) (2z4) is equivalent to which of the following numerical expression? A. 6z8 B. 6z6 C. 5z6 D. 5z8

Answer 1

B.6z6
When you multiply with exponents you add the exponents together 4+2=6
Then just multiply the #s 2×3=6

Answer 2

A.6z8 because all you have to do is multiply 3 and 2 together because they are the number in front of the z and you would get 6 and then you would keep the variable z and then multiply the 2 and 4 together because they both come after the z and you get 8.
