Back with more Qs^^

without calculator

solve for x :

logx = 3loga - logb +logc the answer is a^3c/b

i canceled all the logs and got x =a^3-b+c than i got stuck

simplify:

4^log2 3

i got to 3=2X than i got stuck the answer is 9... 3/2 can't get 9..

whats the value of X :

logx 8=3/4

32=3^x stuck

how can a square root b/c^2 = loga+1/2logb-2logc ?( can't find the root key on the keyboard>.<)
