Question

18*72*105/48*315 = rootx then x is

Answer 1

Solution :

√x = ( 18 × 72 × 105 )/( 48 × 315 )

____________________
i ) 18 = 2×3×3
ii ) 72= 2×2×3×3×3
iii ) 48 = 2×2×2×3×3
iv) 315 = 3 × 105
_____________________

=(2×3×3×2×2×3×3×3×105)/(2×2×2×3×3×3×105)

After cancellation, we get

= ( 3×3 )

√x = 9

Square both sides ,

( √x )² = 9²

=> x = 81
