The dimensional formula of Boltzmann’s constant is,
A=

J

K

=

ML2T−2

K1

=[ML2T−2K−1]
The dimensional formula of Planck’s constant is,
B=Js=[ML2T−1]
The dimensional formula of speed of light is,
C=[LT−1]
The dimensional formula of A4B−3C−2 is,
[A4B−3C−2]=[ML2T−2K−1]4 [ML2T−1]−3[LT−1]−2
=[M1L0T−3K−4]
This is the dimensional formula of Stefan’s constant.
