Question

Find the product. (3a^4 + 4)^2

Answer 1

9a8+24a4+16

Make sure that 8 and 4 are to the power

Answer 2

Answer: The product is
`9a^8+24a^4+16`

Explanation:

Since we have given that

`(3a^4+4)^2`

As we know that

`(a+b)^2=a^2+2ab+b^2`

So, it becomes,

`(3a^4 + 4)^2=(3a^4)^2+2* 3a^4* 4+(4)^2\\\\=9a^8+24a^4+16`

Hence, the product is
`9a^8+24a^4+16`
