please solve the problem with each and every step:
Simplify:
16 x 2^n+1 - 4x2^n
16 x 2^n+2 - 2x2^n+2​

Answer 1

Answer:

Ace

(16*2n+1  -  4*2n) / (16*2n+2  -  2*2n+2)

= (24*2n+1  -  22*2n) / (24*2n+2 -  2*2n+2)        ( by using property  am * an= am+n)

= (24+n+1 - 2n+2) / (24+n+2 - 21+n+2)

= (2n+5-2n+2) / (2n+6-2n+3)

= (2n+2+3-2n+2) / (2n+3+3-2n+3)

= (2n+2)(2n+3-1) / (2n+3)(2n+3-1)

= 2n+2 / 2n+3

= 2n+2-(n+3)                     (by using property  am/an=am-n)

= 2n+2-n-3

= 22-3

= 2-1

=1/2
