Question

if logx 9=2 then value of x​

Answer 1

9=2x

9-2=x

7=x is the answer.....but i am not sure about this....please give me thanks

Answer 2

Step-by-step explanation:

Solve for x log base x of 9=2

logx (9)= 2

in exponential form using the definition of a logarithm. If

x and b are positive real numbers and b≠ 1

, then log b (x) = y is equivalent to by=x. x2= 9

Take the square root of both sides of the equation to eliminate the exponent on the left side.

x =±√9

The complete solution is the result of both the positive and negative portions of the solution.

x=3,−3

Verify each of the solutions by substituting them into

logx(9)=2

and solving.

x=3
