If 4to power x -4to power x-1=24 then find x?
Verified Answer
If 4to power x -4to power x-1=24 then find x?
4^x - 10 � 2^x - 1 = 24

( 2^2 )^x - 10 � 2^x / 2 = 24

( 2^x )^2 - 5 � 2^x - 24 = 0

( 2^x )^2 - 8 � 2^x + 3 � 2^x - 24 = 0

( 2^x ) [ ( 2^x - 8 ) ] + 3 ( 2^x - 8 ) = 0

( 2^x - 8 ) ( 2^x + 3 ) = 0

Therefore ,

2^x - 8 = 0 or 2^x + 3 = 0

2^x = 8 or 2^x = -3

2^x = 2^3

x = 3
