what does log mean? And how would you solve this? y = log x If y = 10, then what is x?

    y=log(x) we assume base 10 if there is no "base" included 10 = log(x) 10^x = 10 x = 1

    x = 10,000,000,000 maybe.. 10 = log(x) 10^10 = 10^log(x) 10^10 = x yep... had it backwards

    Thanks Actually i think you were right the first time because i though it out y = log x 10 = log x 10 = 10^x x = 1

    no, I had it wrong first time, so I worked it out with the rules... your third step there, you need to base10 both sides... 10^10 = 10^log(x) the right hand side become x now 10^10 = x x = 10,000,000,000

    another way to look at is is logs ARE exponents, 10 is the exponent of your base 10. 10^10 = x....

    log2(x) = 3 2^3 = x x = 8 or.... log2(x) = 3 2^log2(x) = 2^3 x = 2^3 x = 8
