Question

2^n+4-2(2^n)+2^-3/2(2^n+3), is equal to​

Answer 1

Answer:

1

written for is given in image

Step-by-step explanation:

2ⁿ⁺⁴   - 2.2ⁿ ) /( 2.2ⁿ⁺³) + 1/8

= (2ⁿ.2⁴ - 2.2ⁿ) / (2ⁿ 2⁴)  +  1/8

Taking 2ⁿ common,

= [ 2ⁿ ( 16 - 2 ) / 2ⁿ 2⁴ ] + 1/8

Eliminating in the equation 2ⁿ,

We have,

=  14/16 + 1/8  = 7/8 + 1/8 = 1
