Evaluating this i can see that both sides of the equation are equal if we de simplify the left side or simplify the right side since 9 is a perfect square....
But problem is i originally attempted to solve this problem by squaring both sides to get rid of the sqrt leaving me with:
I essentially distributed the exponent to the 3 and the sqrt of x individually. Am I not able to do this must i treat them as one somehow?
This is not the same as we now have an inequality. Can someone explain to me what i did wrong... I know it is simpler to just simplify since its a perfect square, but i am not satisfied doin things one way math should always work no matter which way we try to solve an equation.
Opps was suppose to be +1 not 9... Regardless i see that i need to carry that 9 to the x also. Thanks for your help!
Last question regarding steps 4 and 5 of your previous post. What is the logic behind:
Appears I have forgotten something else from class 3 years ago...
