Answer 2

Answer:

3/32...........

Step-by-step explanation:

(2^-3 -2^ -4)(2^-3+2^-4)

here u can see a patter that it is in the foem of (a-b)(a+b) which is equal to a²-b² where a=2^-3 and b=2^-4

so

(2^-3)²-(2^-4)²

(1/2³)²-(1/2⁴)²

(1/8)²-(1/16)²

1/8{(1)²-(1/2)²}

1/8{1-1/4}

1/8*3/4

3/32

hope it helps u
