If v stands for velocity of sound, E is elasticity and d the density, then find x in the equation v = $\left(\frac{d}{E}\right)^x$

1 $\frac{1}{2}$  2 $-\frac{1}{2}$

$-\frac{1}{2}$

V = $\left(\frac{d}{E}\right)^x$ $LT^{-1}=\frac{(ML^{-3})^x}{(MLT^{-2}/L^2)^x}$ LT-1 = L-3x+x T2x -1 = 2x x = $-\frac{1}{2}$
