how to solve (7y5)(2y8+7y6)

Expert Answers

An illustration of the letter 'A' in a speech bubbles

Solve `7y^5 (2y^8+7y^6)`


`7y^5*2y^8 + 7y^5* 7y^6`

When multiplying exponents with the same base the rule is to add  the exponents.

(i.e. `a^2*a^3 = a^5)`

Now apply this rule:

`14y^13 + 49y^11`

Can't add unless variables are the same degree.

The solution is `14y^13 + 49y^11.`
