How to solve logarithmic function?

y = log b x. Then the logarithmic function is given by; f (x) = log b x = y, where b is the base, y is the exponent, and x is the argument. The function f (x) = log b x is read as “log base b of x.”. Logarithms are useful in mathematics because they enable us to perform calculations with very large numbers.

    ln xy= y ln x. log = log x1/y= (1/y )log x. ln = ln x1/y=(1/y)ln x. Example 9:log 5.0 x 106= log 5.0 + log 106= 0.70 + 6 = 6.70. Hint: This is an easy way to estimate the log of a number in scientific notation! Example 10: log (154/25) = log 154 – log 25 = 2.188 – 1.40 = 0.788 = 0.79 (2 sig. fig.)
