Question

Calcule as potências a seguir.

Answer 1

Explicação passo-a-passo:

a) 5³ = 5x5x5 = 125

b) 10⁵ = 10x10x10x10x10 = 100.000

c) 2⁷= 2x2x2x2x2x2x2 = 128

d) 3⁴ = 3x3x3x3 = 81

e)11² = 11x11 = 121

f) 20⁰ = 1

g) (1,8)² = 1,8x1,8 = 3,24

h) (0,4)³ = 0,4x0,4x0,4 = 0,064

i)

${( \frac{2}{3} })^{3} = \frac{ {2}^{3} }{ {3}^{3} } = \frac{2 \times 2 \times 2}{3 \times 3 \times 3} = \frac{8}{27}$

j) (2,5)² = 2,5x2,5 = 6,25

k)

${( \frac{1}{2} })^{4} = \frac{ {1}^{4} }{ {2}^{4} } = \frac{1 \times 1 \times 1 \times 1}{2 \times 2 \times 2 \times 2} = \frac{1}{16}$

l) (3,7)⁰ = 1
