a. 2^5
b. 2^8
c. 2^-8
d. 2^-5

Answer 1

Verified answer

8 x 16 = 128

8^5 = 32.768

=128/32768

Answer 2

^ = pangkat

a ^b × a ^c = a ^(b + c)
a ^b / a ^c = a ^(b - c)
(a ^b) ^c = a ^ (b×c)

2³ × 4² / 8 ^5
= 2³ × (2²)² / (2³) ^5
= 2³ × 2⁴ / 2 ^15
= 2 ^(3 + 4 - 15)
= 2 ^(7 - 15)
= 2 ^-8 (C)

jadi, hasil dari 2³ × 4² / 8 ^5 adalah 2 ^ -8 (C)
