The dimensions of A are M0L0T1 , because the quantities of same dimensions can be added or subtracted .
P = (A-T)2/ Bx [ given equation ]
dimensions of pressure = [M1 L-1 T-2 ]
dimensions of time and distance are [T] and [L] respectively.
By substituting the dimensions in the given equation,
M1L-1T-2 = T2 / BL
[B] = T2/M1L-1T-2L
[B] = M-1L0T4
Dimensions of A/B = M0L0T1/M-1L0T4 = M1L0T-3 = MT-3 .
