Question

What is the product? (7x2y3)(3x5y8)

Answer 1

i don't know if this is the correct answer 3360y^2

Answer 2

Product
`(21) ( x^(7))(y^(11))`.

Explanation:

Given :
`(7x^(2) y^(3))(3x^(5) y^(8))`.

To find : product .

Solution : We have given that

`(7x^(2) y^(3))(3x^(5) y^(8))`.

Combine like terms

`(7 * 3) ( x^(2)*x^(5))(y^(3)*y^(8))`.

By the exponential rule : if the base of two exponent is same then power must be added .
`x^(a) *x^(b) = x^(a+b)`.

Then

`(21) ( x^(2+5))(y^(3+8))`.

`(21) ( x^(7))(y^(11))`.

Therefore, Product
`(21) ( x^(7))(y^(11))`.
