find root of 2^3^4^(x)/4^3^2^x
Read Solution (Total 6)
-
- (2^3)^4^x/(4^3)^2^x=
(8^4)^x/64^2^x=
(64^x*64^x)/(64^x*64^x)=1
its root will be 1 - 11 years agoHelpfull: Yes(3) No(1)
- ex:a^m/a^n=a^m-n
so 2^12x/2^12x
->2^(12x-12x)
->2^0
->1
so the answer is 1

- put x=0;
=1/8 - 11 years agoHelpfull: Yes(1) No(3)
- root(4096^x/4096^x)=1

- 2^3^4^(x)/4^3^2^x = y
Apply log
log ((2^3^2)^2^x/(2^2^3)^2^x) = log y
log 64^2^x/64^2^x = log y
2^x log 64/64 = logy
0 = log y (log 1 = 0)
y = 1

- (((2^3))^4)^x)/
(((4^3))^2)^x)
X gets cancelled
((2^3))^4/((4^3))^2)= ((2^3)^2)/(4^3)=8^2/4^3=64/64=1
