Question

(-1+3)²-2.( √4-√25)+(-20+5-3+2).(-20+10) urgente

Answer 1

$(-1+3)^2-2.(\sqrt{4}-\sqrt{25})+(-20+5-3+2).(-20+10})\\2^2-2.(2-5)-16.(-10)\\4-2.(-3)+160\\4+6+160\\170$

Answer 2

Resposta:

170

Explicação passo-a-passo:

(-1+3)²-2.( √4-√25)+(-20+5-3+2).(-20+10)

(-1+3)²-2.( 2-5)+(-20+5-3+2).(-20+10)

(-1+3)²-2.( 2-5)+(-20+5-3+2).(-10)

(-1+3)²-2.( 2-5)+(-16).(-10)

(-1+3)²-2.(-3)+(-16).(-10)

4-2.(-3)+(-16).(-10)

4-(-6)+(-16).(-10)

4-(-6)+(160)

(10)+(160)

170
