# Math Help - Order of Operations Problem(s)

1. ## Order of Operations Problem(s)

5y^2 + y + 1; y=4

So...

5(4)^2 + 4 + 1

I'm not sure if I am supposed to multiply the 5(4) before I square root it.

5(4)^2 + 4 + 1
= 20^2 + 4 + 1
= 400 + 4 + 1
= 405

Did I work the problem correctly?

$5(4)^2+4+1=5(16)+4+1=\dots$
