Simplify seven square root of three end root minus four square root of six end root plus square root of forty eight end root minus square root of fifty four. eleven square root of six end root minus seven square root of twelve eleven square root of three end root minus seven square root of six negative three square root of nine four square root of nine

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
