I am wondering if I did this right?
Write Using a positive exponets and simplify if possiable.
(-3x)^2
I took the -3^2=9 over the x^2
and the answer would be
- 9 over x^2
no. If if it
(-3x)^2, that is equal to 9x2
To simplify the expression (-3x)^2 using positive exponents, you need to square both the base and the exponent of -3x separately.
First, you square the base (-3)^2, which gives you 9.
Next, you square the exponent x^2, leaving it as x^2 since it is already raised to the second power.
So the simplified expression is 9x^2, not -9/x^2.
To check your work and ensure that the expression is simplified correctly, you can substitute a value for x into both the original and simplified expressions and verify that they give you the same result.
