Question

Radical problem: square root of 50 minus square root of 32 + square root of 18= ??

Answer 1

\[\sqrt{50}-\sqrt{32}+\sqrt{18} = \sqrt{25*2}-\sqrt{16*2}+\sqrt{9*2}= \sqrt{2}(5-4+3)=4\sqrt{2}\] will be the answer i hope...

Answer 2

how did you get this @sriramkumar ? √(5−4+3)

Answer 3

take sqrt(2) common frrom all the terms you see... @alfers101

Answer 4

each of those square roots can be simplified.

to simplify a surd you look for the highest square number that can possibly go into that number
so for root 50
what is the highest square number to go into 50?
25
you multiply it by 2

this allows you to re write root 50 into
root 25 x root 2

root 25 is 5
so you have 5xroot2
which is 5root2

follow the same process with your other square roots
then you just subtract the coefficient of each square root and have the same root (root 2)

Answer 5

thank you :D
