The number of solutions of x+ ₀^x In t d t= x^2 3 , (x R ⁺ ) is __________ .

Correct answer

2

Step-by-step solution

t t- .t |₀ ^x+x= x^2 3 x= x 3 Now equation of tangent of the slope 1 3 to the curve y= x at (3, 3) is y- 3= 1 3 (x-3) y= 1 3 x+( 3-1) As, 3-1 0 , this tangent is above the line y= x 3 . So the line y = x 3 will cut y = x at two distinct points.
