Question

ajudaaaaaaaa pfvr !!!

Answer 1

Olá vou apenas dar a resolução,daria para explicar,mas é muita coisa

a) R: 0

$- 7 {}^{2} + ( - 7) {}^{2} \\ = - 49 + 49 \\ = 0$

b) R: -37

$- 2 {}^{3} - 30 + 1 = \\ - 8 - 30 + 1 = \\ - 37$

c)R: 35/27

$( \frac{2}{3} ) {}^{3} + 1 \\ = \frac{8}{27} + 1 \\ \frac{35}{27}$

d)R:-26

$- 5 {}^{2} + ( - 3) {}^{2} 10 = \\ - 25 + 9 - 10 = \\ - 26$

e)R: 0

$-3 {}^{2} + 3 {}^{2} = \\ = 0$

f)R: 7/4

$5 {}^{0} - ( - 1) - ( - \frac{1}{2} ) {}^{2} = \\ 1 + 1 \frac{1}{4} = \\ 2 - \frac{1}{4 } = \\ = \frac{7}{4}$

g)R: 35/48

$(1 - \frac{1}{2} ) {}^{4} + (1 \\ + \frac{1}{2} ) {}^{ - 1} = \\ = ( \frac{1}{2} ) {}^{4} + ( \frac{3}{2} ) {}^{ - 1} \\ = \frac{1}{16} + \frac{2}{3} \\ = \frac{35}{48}$

Bons estudos!
