Answer 1

Oi...

Calcule:

a)

(1/2)²  = 1²/2² = 1/2 × 1/2 = 1/4

b)

(1/3)⁴  = 1⁴/3⁴ = 1/3 × 1/3 × 1/3 × 1/3 = 1/81

d)

(2/3)⁵ = 2⁵/3⁵ = 2/3 × 2/3 × 2/3 × 2/3 × 2/3 = 32/243

e)

(3/2)²  = 3²/2² = 3/2 × 3/2 = 9/4

f)

(1 1/2)³  = (3/2)³ = 3³/2³ = 3/2 × 3/2 × 3/2 = 27/8

g)

(4/3)²  = 4²/3² = 4/3 × 4/3 = 16/9

i)

(1/2)³ = 1³/2³ = 1/2 × 1/2 × 1/2 = 1/8

j)

(2 7/4)² = (21/4)² = 21²/4² = 21/4 × 21/4 = 441/16

k)

(3 1/3)³ = (10/3)³ = 10³/3³ = 10/3 × 10/3 × 10/3 = 1000/27

l)

(5/6)² = 5²/6² = 5/6 × 5/6 = 25/36

m)

(7/8)³  = 7³/8³ = 7/8 × 7/8 × 7/8 = 343/512

n)

(2/5)⁴ = 2⁴/5⁴ =  2/5 × 2/5 ×  2/5 × 2/5 = 16/625

Espero ter ajudado.
