(-3x)-^2
Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! write using positive exponents, and simplify if possible.
(-3x)^-2
-------
The negative exponent means "invert"
The 2 mean "square"
--------
You get:
If you square first: (9x^2)^-1
If you then invert: 1/(9x^2)
-----------
If you invert first: 1/(-3x)^2
If you then square: 1/(9x^2)
