Question

Simplify the following 4 square root of 3 - 2 square root of 2 cbsc 9th number sysytem

Answer 1

here 4 = squareRoot of 16
now,
LHS=squareroot of 16 ×sqaureroot of 3
=SquareRoot of 48

and in RHS,
2 = root2 × root2
now RHS become
Root2 ×root2×root2=root8
Therefore LHS-RHS=root48-root8
=root40 is the answer.
Also,squareroot of 40=6.32(approx)
