How to evaluate the expression: log 10,000,000

log(10,000,000)
=log(10)^7
=7log(10)
=7(1)
=7 answer//

When we are doing log...... and if the first digit is 1 (one) and followed by any number of 0 (zero) or 0's (zeroes) the answer will be the number of zeroes. In this case number of zeroes is 7 (seven). Then the answer 7 (seven). You don't need a scientific calculator.

Example: log 10 is 1
log 100 is 2
log 1000 is 3
log 10000 is 4..........................and so on

log (10,000,000) = x

10,000,000 = 10^x

when you have a large number of 1 followed by a lot of 0's, just count the 0's and that number is what you set x as in 10^x. here you have 7 0's so the answer is:

10,000,000 = 10^7, so x = 7

If you are told to do the working;

log 10,000,000 = X

10,000,000 = 10^x

X = 7, since 10^7 is equal to 10,000,000.

log (10,000,000) = log (10^7) = 7 × log(10) = 7 × 1 = 7

all this is asking is "10 to what power equals 10,000,000" once you think about it that way than it should be easy

Put it in a scientific calculator
and you get the answer as 7

Count the zeros. log 10,000,000 = 7
