Evaluate 10^{y} = 0.000001

**Solution:-**

Note that by convention, log _{10}x is simply denoted log x. To evaluate log 0.000001, that is , log _{10}0.000001, write y = log_{10}0.000001 in its equivalent exponential form.

10^{y} = 0.000001

Express 0.000001 as the power of 10.

10^{y} = 0.000001

=10^{-6}

Therefore, log 0.000001 = -6
