For a given expression of power, `P= (a)/(bx)-(t^2)/(b)`.
Determine the dimensions of a and b. Here, x and t are distance and time respectively.

Explanation

To determine the dimensions of \( a \) and \( b \) in the expression for power given by

\[ P = \frac{a}{bx} - \frac{t^2}{b}, \]

where \( x \) is distance and \( t \) is time, we will follow these steps:
