1.logbase8(2)

2.logbase10(1.25)+logbase10(80)

how do you start out ? i forgot all about logarithym.s please help with step my steps

- calculus -
**drwls**, Wednesday, September 26, 2007 at 2:15amThis is not calculus.

Log(base8) of 2 is what power x of 8 you must have so that 8^x = 2

2 is the cube root of 8, so the answer is 1/3.

2. logbase10(1.25)+logbase10(80)

= log(base10)(1.25*80)

= Log(base10)(100)

What is the number x such that 10^x = 100 ?
