Question

Which expression is equivalent to x4 • x−2?

Answer 1

Hey there!

The second "$x$" is has  invisible $1$

Here, this is what I meant: $x^ 1$

So, now your equation looks like this: $x^4(x^1$ $-2)$

Add the exponents: $4 + 1$ $= 5$

Therefore your answer should be: $x^5 - 2$

(Note: there's many ways to solve these types of equations, I just gave you the basic method)

Good luck on your assignment and enjoy your day!
