Question 475188
log(3)5+log(3)x=log(3)10
{{{log(3,5) + log(3,x) = log(3,10)}}}
Adding logs --> multiply
{{{log(3,5x) = log(3,10)}}}
5x = 10
x = 2
-----------------
log(1/7)x=-1
Is that log of (x/7) ? or log or x*log(1/7) ?
-------------------
2ln3x+1=5
2ln(3x) = 4
ln(3x) = 2
3x = e^2
x = e^2/3
----------
log(3)0.1+2log(3)x=log(3)2+log(3)5
Similar to the 1st one.
--------------
log(b)9=2
b^2 = 9
b = 3
---------------
1/4log(2)16+1/2log(2)49=log(2)2x
Similar to the 1st one.
----------------------
3^2m=16^-1
Is 2 the exponent?  or 2m?
----------------
4^ex-5=1
4^ex = 6x
ex = 6^(1/4)
x = 6^(1/4)/e
