Question

solve : 2^x+2 + 2^x-2 = 34 please i have to give answer now​

Answer 1

Answer:

2^x+2 + 2^ x-2= 34

2^(X+2)+(x-2)= 34

2^2x = 34

2^2x= 32+2

2^2x= 2⁵+ 2¹

now, on comparison,

2x= 5+ 1

2x= 6

x= 3

Hope this helps

Answer 2

Answer:

2^x+2 + 2^x-2 = 34

2^ x * 2^2 + 2^x / 2^2 = 34

2^ x ( 4 +1/4 ) = 34

2^ x  ( 17/4 ) =34

2^ x = 34 * 4 /17

       = 8

      = 2^ 3

therefore x=3 (answer )
