Question

number of solution of eqution: logx=x (where,base of log is 1.1)​

Answer 1

Answer:

This is the key to solving equations in which logarithms appear.

For example: Suppose we want to solve the equation log2 y = 3. Since this means exactly the same thing as 23 = y, the equation pretty much solves itself!!

Here's a slightly harder problem: Solve the equation log2 (5z+ 1) = 4. Since this means exactly the same thing as 24 = 5z+1 , we need only solve the ordinary equation 16 = 5z +1 . So the solution is z = 3.
