Solve for x: 10^ (2+logx) = 21

Step-by-step explanation:

Determine the defined range

Take the logarithm of both sides of the equation

Convert the constant into a logarithmic with base 10

Using loga (x) + loga (y) = loga (xxy)

Evaluate the power

Since the base is based of the logarithmic are the same, set the argument equal

Divide both sides of the equation by 100

Check if the solution is in defined range

Answer: 21/100
