Question

What is the product of -3x5y2 and 9x3y8?

Answer 1

For this case we must find the product of the following expression:

`(-3x ^ 5y ^ 2) * (9x ^ 3y ^ 8)`

Then, by definition of powers of the same base we have to put the same base and add the exponents:

`(-3 * 9) x^(5 + 3) (1 * 1)y^(8 + 2) =`

`-27x ^ 8*1y ^ {10}`

ANswer:

`-27x ^ 8y ^ {10}`
