What 'logarithm base are you using.
If Base '10' per calculator
The log(10)125 = 2.09691
However, You can use logs to any base So if we use base '5'
Then
log(5)125 = 3 Because 125 = 5^3

log(5)125 = log(5) 5^(3) = 3log(5) 5 = 3 (1) = 3 Remember for any log base if the coefficient is the same as the base then the answer is '1' Hence log(10)10 = 1 log(a) a = 1 et.seq., You can convert the log base '5' , to log base '10' for ease of the calculator. Log(5)125 = log(10)125/log(10)5 Hence log(5)125 = log(10) 5^(3) / log(10)5 => log(5)125 = 3log(10)5 / log(10)5 Cancel down by 'log(10)5'. Hence log(5)125 = 3 NB one of the factors of 'log' is log(a) a^(n) The index number of 'n' can be moved to be a coefficient of the 'log'. Hence log(a) a^(n) = n*log(a)a Hope that helps!!!!!
125 x 125 = 15625
20 percent off 125 = 10020% off of 125= 20% discount applied to 125= 125 - (20% * 125)= 125 - (0.20 * 125)= 125 - 25= 100
The GCF is 125.
1*125=125 or 5*25=125
