Question

Y 7 • y 9

Multiply or divide as indicated.

Answer 1

For this case we have the following expression:

`y^ 7 * y^ 9 =`

By definition of multiplication of powers of the same base, we have to put the same base and add the exponents, that is:

`a ^ n * a ^ m = a ^ {n + m}`

So:

`y ^ 7 * y ^ 9 = y ^(7 + 9) = y ^ {16}`

Answer:

`y^(16)`
