You can put this solution on YOUR website! If I am understanding what you have presented here, the equation would be .
Is this correct?
Assuming it is...
Let us begin by separating terms inside and outside of the radical sign.
Roots may be multiplied and grouped together under the same radical sign, as long as the index is equal for the roots in question.
Therefore, roots can also be separated by their respective divisors. So our equation becomes...
We use these specific factors of the numbers because it allows us to take a square root. Specifically, 9 and x^2 are perfect squares. So we can simplify further now...
and now to complete the groupings...
Check your answer! Since this is not an equation, you can choose any two numbers, one to represent 'x' and one to represent 'y'.
If your finished simplified form calculates equally to the first, then you know that at least, the simplification that you did is correct (Though it may be possible that there is further simplification to be done).
I hope this helps! Learn on
