All you have to do in this question is open the brackets like this:
192 - 64x  = 42x
And then bring all x values to one side and then find x.
That's pretty much it! :)

Opps now that I look at it, the problem didn't go the way it was suppose to

64^(3-x) = 4^2x

akashdeepdeb · Answer

haha...
Write 64 as 4^3 and multiply 3 to 64's power
What i mean is that. 64^(3-x) can also be written like 4^3(3-x)
And this is equal to 4^2
Now we know if BASES (here, 4) are equal then the powers should also be the SAME.
So here 3(3-x) = 2
Now just solve it by openning the brackets and find the x balue! :)
Got it? :)
