4^x + 2^(2x - 1 ) = 3^( x + 1/2 ) + 3^(x - 1/2)
By taking 3^ ( x - 1/2 ) as common from R.H.S,
(2^2)^x + 2^( 2 x - 1 ) = 3^( x - 1/2 ) ( 3 + 1 )
2^(2x ) + 2^( 2x- 1 ) = 3^( x - 1/2 ) 4
By taking 2^( 2x - 1 ) as common fron L.H.S,
2^(2x - 1 ) ( 2 + 1 ) = 3^( x - 1/2 ) * 2^2
2^( 2x - 1 ) * 3 = 3^( x - 1/2 ) *2^2
As bases are equal , so exponent must be equal,
2x - 1 = 2 or 1 = x - 1/2
2x = 2 + 1 or 1 + 1/2 = x
2 + 1
2x = 3 or --------------- = x
2
x = 3/2
or x = 3/2.
So, x = 3/2.
