    Okay, so what do you get in the equation when you plug \(\rm y = 10\)?

    10 = log x x = 10^10 you raise both powers to whatever the base of the log is to get rid of the log

    Whenever you have such a form, then I prefer the exponential form.

    @ParthKohli if x and y were reversed, this would be true

    if you do log(1) you dont get 10

    \[\rm 10 = \log (x)\]Right? But here, the base is 10.

    so raise both sides to the 10th power to get rid of the log with base 10

    the exponential form \(\huge if, a=log x\implies x=10^a \)

    so what will be 10=log x ?

    but its y=logx then you get 10^x x=1 right?

    \[\rm y = \log_{10}x \]So,\[\rm 10^y = x\]Right?

    Now if you have y = 10, then you have\[\rm 10^{10} =x \]Got my point?

    And that's your answer! If you prefer the numeric notation, then add ten zeroes in front of 1.
