Do you know your basic logarithmic rules?
Alright well for the first one I would do Ln(1/2) ^x = ln15 then you can bring the exponent in front therefore giving you xln(1/2) = ln 15. Then you get x= ln (15) / ln(1/2)
for the second you have the rule of Log(a)b= c is the same as a^c = b

ok..so how do i solve 2?
you have a ruole saying a√x = √b . Both a and b are constant.
Therefore in this case you would have
x =729 ending up as ( because what you do on the left you ahve to do on the right)
3 √x^3 =3√729 You should have a button on your calculator labelled as x√
err sorry I meant the rule is a√x^a = a√b
where the a's in : a√x^a cancel out. ( same as a square root and a square)
Do you understand or I made it too complicated?
kind of complicated..
alright I'll try to water it down.
You know sqrt(x) = (x)^1/2 right?
You have probably learned in algebra sqrt(x^2) ends up as X only because the sqrt cancels out with the square (^2)
if you have x^3 = 729, you don't have an answer you WANT X= ?
Therefore, you have to CANCEL OUT the ^3 somehow.
The only way, like how you cancel a ^2 is by SQUARE ROOTING THE EXPRESSION
so you end up with 3(sqrt)(x^3) = (x^3)^(1/3). By the rule of exponent, you multiplied the 2 of the ( 3*1/3) = 3/3 = 1
GIVING YOU X
WHAT YOU DO ON THE LEFT YOU DO TO THE RIGHT
the answer should be 9
I'm sorry if I made this too complicated, I just tried to explain the concept to it
