a) 143 =
b) (3%5) = (3)
c) (3%5)2 = (3)​

Answer 1

Explicação passo-a-passo:

a) 14³ = 14 × 14 × 14 = 2744

b) (3/5)² = 9/25

c) (3/5)^-2 = (5/3)² = 25/9

Answer 2

Oie, Td Bom?!

>>> Resolvendo as expressões.

a)

$14 {}^{3}=14 \times 14 \times 14=2744$

b)

$( \frac{3}{5} ) {}^{2} = \frac{3 {}^{2} }{5 {}^{2} } = \frac{9}{25} = 0,36$

b)

$( \frac{3}{5} ) {}^{ - 2} = ( \frac{5}{3} ) {}^{2} = \frac{5 {}^{2} }{3 {}^{2} } = \frac{25}{9} ≈2,777...$
