Question

Simplify: (16x5 + 8y2) – 7x5

Answer 1

You can combine terms that have the same variable to the same power
Here you have
\[ 16x^5 + 8y^2-7x^5 \]
the \(x^5 \) is in two different terms. You can "add" them
\[ 16x^5 -7x^5+ 8y^2 \]
or
\[ (16x^5 -7x^5)+ 8y^2 \]

If you have 16 of something and take away 7, how many do you have?

Answer 2

what did you get?

Answer 3

I got, 9x5 - 8y2.

Answer 4

I hope you mean 9x^5 + 8y^2

it is plus not minus on the y^2 term

Answer 5

Yeah. That's what I meant. That's what I have down on my paper. Thanks for the help.
