A^x = A⁵

then x = 5. This is incomplete ?

simple.. A^5 is the equation.

the answer is unknown unless you find the value of A.

MacGyver said...: I don't understand the problem. If A^x = A^5, then x must equal 5, and the A's must equal each other.

This isn't a trick at all. Maybe the trick is that there is no trick? lol; September 25, 2008 10:44 AM

Anonymous said...: no x and five are both exponents. you assume that both a's are the same. with your assumptions only is it correct. but both a's do not have to be the same.; September 27, 2008 2:31 PM

x=5 if A is not equal to 0 or 1

if A=1 x could be any number

if A=0 x could be any positive number; September 29, 2008 3:31 AM
