btw please show how you did it, i want to learn how to do this type of log because im kinda interested
I do have an answer for question1
let A=3^x and B=2^x
Do the substitution and then solve as a quadratic.
5. We can write
(1/3) ( log x / log 2) + (log x /log 2)^(1/3) = 4/3
Let Logx /log 2 = a
And we have
(1/3)a + a^(1/3) = 4/3 rearrange as
a^(1/3) = 4/3 - (1/3)a
a^(1/3) = (4 - a) / 3 cube both sides
a = (4 - a )^3 / 27
Note that this is true when a = 1
So a = log x / log2 = 1 → x = 2
2 .√ ( log 3 x9) - 4log 9 √(3x) = 1
√ (log 3 x9) - log 9 √(3x)4 =1
√(log 3x 9) - log 9 (3^2 x2) = 1
√ (log 3 x9) - log 9 3^2 - log 9 x2 = 1
√(9log 3 x) - log 9 9 - log 9 x2 = 1
√(9log 3 x) - 1 - log 9 x2 = 1
√(9log 3 x) - 2 log 9 x = 2
3 ( log 3 / log x)^(1/2) - 2 (log x / log 9 ) = 2
3 ( log 3 / log x)^(1/2) - 2 (log x / log 3^2) =2
3( log 3 / log x)^(1/2) - 2 (log x /(2 log 3) ) = 2
3 ( log3/ log x)^(1/2) - log x /log 3 = 2
3 (log 3/logx)^(1/2) - 1 / (log 3/logx) = 2
Let (log 3/log x)^(1/2) = a
Then log3/logx = a^2
So we have
3a - 1/a^2 = 2 multiply through by a^2
3a^3 -1 =2a^2
3a^3 - 2a^2 = 1 and it's clear that this will be true when a = 1
So (log 3 / log x)^(1/2) =1 square both sides
log 3 / log x = 1
x = 3
