what are the solutions?

Answer 1

i believe there is no variable?

Answer 2

Zion? What is this? solutions of what?

Answer 3

i mean how are you going to solve this one? some equations.

Answer 4

equations have variables like x and y.. then you solve to find the solutions of x and y

Answer 5

say for eg log base 10(x)=1 haas a solution x=10..

Answer 6

\[\log_{10}x=1 \]

Answer 7

it is an identity! damn! log sub8 (1) = 0

Answer 8

i believe sub mans base?

Answer 9

yes it is log of 1 is 0

Answer 19

do the brackets. solve whats inside each bracket and work outwards!

Answer 20

another one : \[\log_{8}X=8 \] and \[\log_{8}Y=9 \] ... what is \[\log_{Y}X=?\]

Answer 21

do you know the property log sub b a= (log a)/log b to any sub?

Answer 22
