Question

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

Answer 1

Answer:the answer is c

Explanation:

Answer 2

The product of
`(7x^(2)y^(3))(3x^(5)y^(8))` is
`=21x^(7)y^(11)`

Explanation:

We need to find product of expression :
`(7x^(2)y^(3))(3x^(5)y^(8))`

`\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^(b+c)`

`=7y^3\cdot \:3x^(2+5)y^8`

`=7y^3\cdot \:3x^7y^8`

`=7\cdot \:3x^7y^(3+8)`

`=7\cdot \:3x^7y^(11)`

`\mathrm{Multiply\:the\:numbers:}\:7\cdot \:3=21`

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

Therefore, the product of
`(7x^(2)y^3)(3x^(5)y^(8))` is
`=21x^(7)y^(11)`
