Answer:
Speed of light C=[LT −1 ]
gravitational constant G=[M −1 L 3 T −2 ]
planck's constant h=ML 2T −1
Let M=C x G y h z
[M]=[LT −1 ] x [M −1 L 3 T −2 ] y [ML 2 T −1 ] z
[M]=[M −y+z L x+3y+2z T −x−2y−z ]−y+z=1,x+3y+2z=0,−x−2y−z=0
On solving, we get
x= 21
;y= 2−1
;z= 21
So, dimension of M=[C 1/2G −1/2 h 1/2 ]
