Question

05. Calcule o valor de cada uma das potências a seguir: a) 2² = b) (–5)² = c) 10² = d) (–1)³ = e) 4² = f) 5² = g) (3 + 7)² = h) (10 + 1)² = i) (6 – 3)² = j) (8 – 10)² =​

Answer 1

a) 2² = 2 × 2 = 4

b) (–5)² = (–5) × (–5) = 25

c) 10² = 10 × 10 = 100

d) (–1)³ = (–1) × (–1) × (–1) = –1

e) 4² = 4 × 4 = 16

f) 5² = 5 × 5 = 25

g) ( 3 + 7 )² = 10² = 10 × 10 = 100

h) ( 10 + 1 )² = 11² = 11 × 11 = 121

i) ( 6 – 3 )² = 3² = 3 × 3 = 9

j) ( 8 – 10 )² = ( –2 )² = (–2) × (–2) = 4
