log(400)
so 10 to the power of 2.602..... = 400?
can this go into a fraction?

okay thank you so much! I've followed you

calculate log(base 10) 400?
HOW THE HELL DO I DO 10^X = 400???
DON'T KNOW HOW TO DO THESE
HOW THE HELL DO I DO 10^X = 400???
DON'T KNOW HOW TO DO THESE
10^x =400, so take logs on both sides so, xlog10=log400, divide both sides by log10 so X=log400/log10 --> stick that in ur cal and u get value of X.

Type this in your calculator
Log 400/log 10
and you will get x
Log 400/log 10
and you will get x
thank you
what about 5^2x = 7^x+1 ?? how would I work out x? x

Write 400 as some number multiplied by some power of 10, then use log laws to rearrange.

As far as I can tell there's no way to get an exact answer to this one. Are you sure you don't mean 7^(x+1)?
