Default can someone help me with my math homework?

easy stuff

i just want to know how to do this


first:

X=Log5 36


and

2(log a 3 + Log a X) - 1/2(log a 4 + log a 9)

and

82600 x 0.035 - 85.2

this one has to be solved using logs


if someone or anyone could explain any of these, i'll love you. this is university level math btw, its just a review and im drawing a blank

Sorry dude, I am in law school, and our contract specifically says that we (the law students) will not be subjected to math in any way shape or form.

However, there are a lot of math geniuses in here, but sometimes they are dicks.

X=log5 36
means:
5^x = 36 ... to solve quantitatively on a calculator:
x = log10(36)/log10(5)

2( loga(3)+loga(x) ) - 1/2( loga(4) + loga(9) )
i assume they want you to simplify?
that equals:
loga(3^2)+loga(x^2) - ( loga(4^1/2) + loga(9^1/2) )
where ^ denotes exponent, e.g. 9^1/2 is nine to the one half power, or equivelently, square root of nine...
= loga(9)+loga(x^2) - (loga(2) + loga(3) )
= loga((9x^2)/6) = loga((3x^2)/2)

don't know what they want in that last one... scientific notation maybe?

Couldn't you use a calculator?

How did the mathematician get rid of his hemerroids?

He worked them out with a pencil.
