(root18 +root2)sqaured/(root8-2). Give answer in form A(B+rootC) where A,B and C are integers
root 18 = 3root2root8 = 2root2
Numerator: (3root2+root2)squared = (4root2)squared =32Denominator: 2root2 -2 = 2(1-root2)Simplify both numerator and denominator by dividing by 2 resulting in numerator to be 16 and denominator to be 1-root2Rationalise the surd by multiplying with 1+root2 giving you the answer 16(1+root2)
