The length of the subtangent at any point

\left( {{x_1},\;{y_1}} \right)

on the curve

y = {a^x},\;(a > 0)

View answer and explanation

Correct option: B

\frac{1}{{\log a}}

Option B (

\frac{1}{{\log a}}

) is correct because it represents the length of the subtangent calculated using the derivative of the curve and the formula for subtangent length.
