Question

Find the greatest common factor: 30y8 + 10y4

Question 1 options:



y2



20y2



10y4



10y8

Answer 1

`10y^4`

Explanation:

The first term is divisible by the second term, which means that the second term itself is the greatest common factor. If you factored it out you would be left with:

`10y^4(3y^4 + 1)`
