Wolfram alpha vs symbolab

[Eingram]

I'm reviewing algebra 1. I noticed that in cases involving negative and fractional exponents, wolfram alpha and symbolab give different answers. Each says the other is wrong. Which is right?

Come on! How are we expected to have any idea what you are asking? Tell us about the problem.

 

[Eingram]

(x^-5/3y^-1)^-2
Is one example.

From Wolfram Alpha: 1/(x-5y/3-1)^2

Symbolab: 9x^10/y^2

I assume this is the question you are trying to input:
[MATH]\left(\frac{x^{-5}}{3y^{-1}}\right)^{-2}[/MATH]
I'm not sure I understand the output you got from Wolfram Alpha, but Wolfram is sensitive to brackets (or their absence).
You need to bracket the top line and bracket the bottom line.
Input it like this:
([MATH]\hspace1ex[/MATH] ( x^(-5) ) / ( 3y^(-1) )[MATH]\hspace1ex[/MATH])^-2
and you get the correct result from Wolfram Alpha (in agreement with Symbolab):
