can anyone change negative exponents to positive

OpenStudy (anonymous):

send it down

OpenStudy (anonymous):

Sure, if you switch from the numerator to denominator or vice versa.

OpenStudy (anonymous):

Example: x^(-3) = 1/x^3

OpenStudy (anonymous):

how would you do (5x^2)^-1

OpenStudy (anonymous):

Or here's another example if you have 3/x^(-5) you can "move" the x to the numerator and it becomes 3x^5.

OpenStudy (anonymous):

how would you go about my problem

OpenStudy (anonymous):

Both the 5 and the x^2 are affected by the power of -1. If they are in the numerator right now, where do you think they'll end up?

OpenStudy (anonymous):

denominator

OpenStudy (anonymous):

Excellent!

OpenStudy (anonymous):

how would you write it out tho

OpenStudy (anonymous):

I'll wait here why you try to give me an answer. Have a guess if you're not sure.

OpenStudy (anonymous):

would it just be 5x since you minus an exonent

OpenStudy (anonymous):

Good guess. If you just make the x an "x^2" you'll have it! 5x^2.
