Answer 2

Answer:

(1) 2^5÷2^-6 = 2^11

(2) (2^5÷2^8)×2^-5 = 2^-20

(3) (-4)-³×(5)-³×(-5)-³ = 4-³×5^-6

(4) 1/8 ×(3)-³ = 6-³

(1) 2^5÷2^-6 = 2^5/2^-6

= (2^5)(2^6)

= 2^(5+6)

= 2^11

= 2048

(2) (2^5÷2^8)×2^-5 = (2^5×2^-8)^5×2^-5

= (2^-3)^5(2^-5)

= (2^-15)(2^-5)

= 2^(-15-5)

= 2^-20

(3) (-4)-³×(5)-³×(-5)-³ = 1/4³×1/5³×1/5³

= 1/4³×1/5(³+³)

= 1/4³×1/5^6

= 4-³×5^-6

(4) 1/8 ×(3)-³ = 1/2³ × 1/3³

= 1/8 ×1/27

= 1/216

= 1/6³

= 6-³
