Detailed Solution

Given equation is 3x2-2x3=log2x2+1-log2x.

It is required to find the number of solutions which satisfies the given equation.

Using the basic logarithmic property, logm-logn=logmn

3x2-2x3=log2x2+1-log2x 3x2-2x3=log2x2+1x

Writing the equation in exponential form

23x2-2x3=x2+1x

x is not defined when x=0, 2,3

Only x=1 satisfies this equation.

Hence, number of solutions for the given equation is 1.

Therefore, the correct answer is option 3.
