4^(4x)=4
take log on both the sides
4xlog4=log4
4x=1
x=1/4
x^4=(1/4)^4=0.0039=0.004

pawan kumar   9 years AGO

[4^X]^4= 4^4X=4
so, 4X=1
X=0.25

so, X^4=0.25^4=0.0039
=0.004

[4^X]^4= 4 put x= 0.25
Then 0.25^4= 0.0039
So ans is 0.004

ADERU CHENCHU NITHISH   9 years AGO

(4^x)^4=4
log(4^4x)=log4
4xlog4=log4
4x=1
x=0.25
so x^4=(0.25)^4=0.0039=0.004

SHAHEEN   9 years AGO

[4^x]^4 = 4
4^(4x)=4
we can equate powers if bases are equal
=> 4x=1
x=1/4
x^(1/4)=0.00390625==0.004(appr.)
so the ans is option 4.

KARRI V V S B VAMSI KRISHNA REDDY   9 years AGO

[4^x]^4 = 4
4^4x = 4
as bases are equal power should be equal
4x = 1
x = 1/4
therefore X^4 = (1/4)^4 = 0.0039265 = 0.004

AMIT KUMAR   9 years AGO

we can write 4^4x=4
taking log both side then
4x * log4 = log4
x=1/4
so, (1/4)^4= 0.00390~0.004

Ravi Kumar Kodari   9 years AGO

Given, [4^x]^4 = 4
by solving this we get, 4x=1 so, x=1/4.

(1/4)^4=0.0039=~0.004 Ans.
