Caution:- I am very very dumb at math!
Please help me with couple of question & let me know the method of solving:-
Q1- If a (exponent or is to power) [color=red]b a^b=4, and 3b=2, what is the value of [size=150]a[/size]?
since b = (2/3), we can rewrite a^b and change that into a^(2/3).
Now:
a^(2/3) = 4
the trick for all exponent problems is that you have to get all the numbers into prime bases. so we turn that 4, into 2^2:
a^(2/3) = 2^2
We can then take both sides to the (3/2) power (so that the 2/3 cancels out):
[a^(2/3)]^(3/2) = [2^2]^(3/2)
You will now see that:
a = 2^3 = 8
