POR FAVOR ME AJUDEM NESSAS QUESTÕES! !

Anexos:

jessicahengen: vou procurar de novo

thalia054: Não tem problema não ok

jessicahengen: vou pedir para o meu professor

thalia054: Obrigada!

jessicahengen: Na potenciação com bases iguais, quando se multiplica a base soma-se os expoentes. E quando se divide as bases, diminuem-se os expoentes.

O expoente negativo inverte a base.

Quando trabalhamos com divisão de fração, a segunda passa multiplicando, invertida.

jessicahengen: e) (-1,1).(-1,1)^-3.(-1,1)^-2

(-1,1)¹⁻³⁻² =

(1,1)⁻⁴ = 1/(1,1)⁴=

1/1,4641

jessicahengen: g)[(0,5)^-4:(0,5)^-9]^-2:(0,5)^-5

[1 /0,5⁴ - 4/1/0,5⁹] ⁻² - 2/1/0,5⁵

[1/0.0625 - 4.0.001953125]⁻² - 2. 0,03125

[16 - 0.0078125]⁻² - 0,0625

[ 15,99] ⁻² - 0,0625

(1/15,99)² - 0,0625

-0.058

h)[(3/5)^3:(3/5)^-4]^-2

[27/125 / 81/625] ⁻²

[27/125 . 625/81] ⁻²

[2187/ 78125 ] ⁻²

(78125/2187)²
