Question

a) (3/5) la putere 2; b) (-3/5) la putere 2; c) (1/4) la putere3

Answer 1

Răspuns:

Explicație pas cu pas:

a) (3/5) la putere 2 = 3²/5² = 9/25

b) (-3/5) la putere 2 = (-3)²/5² = 9/25

c) (1/4) la putere 3 = 1³/4³ = 1/64

Answer 2

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

$(\frac{- 3}{5} ) ^{2} = ( \frac{3}{5} ) {}^{2} = \frac{3 {}^{2} }{5 {}^{2} } = \frac{9}{25}$

$( \frac{1}{4} ) {}^{3} = \frac{1 {}^{3} }{4 {}^{3} } = \frac{1}{64}$
