Answer:

x = 50

Step-by-step explanation:

log_{10}(2x)  = 2

Use the following property.

log_{a}(m)  = n \\  {a}^{n}  = m

{10}^{2}  = 2x \\ 100 = 2x \\  \frac{100}{2}   = x \\ 50 = x

Therefore, the value of x is 50.

<u>Answer</u><u> </u><u>Check</u>

Substitute x = 50 in the equation.

log_{10}(2x)  = 2 \\  log_{10}(2(50))  = 2 \\  log_{10}(100)  = 2 \\  {10}^{2}  = 100 \\ 100 = 100

The equation is true. Therefore x = 50.

<u>Note</u>

If you don't write logarithm with base, it is classified as common logarithm or base 10.
