i need help on this problem right here can you please help me
?

3 square root of 108 -2 square root of 18 -3 square root of 48

 

[tkhunny]

\(\displaystyle 3\sqrt{108} -2 \sqrt{18} -3 \sqrt{48}\) ?

Is there a problem statement?

I expect it's a "simplify" problem. In this case, you need to go on a safari, searching for perfect squares.

108 = 9*12 = 9*4*3
18 = 9*2
48 = 4*12 = 16*3

See if that leads anywhere.

Its a "Add or Subtract problem" but what i dont get is when i solved the equation the square root of 108 was not there when i checked the answer in my book. i dont get how it got rid off
