Answer 1

Resposta:

(-2-5)2 (1) 2.-5. (-3): √-7+16] o colhete fecha no final? se não tera que refazer.

(-7)2.1.(-2). [-5. (-3):√9] 49.1.(-2).[-5.(-3): 3]

49.1.(-2) [15:3]

49.1.(-2).5

⚫ 49.(-2).5

⚫ -98.5--490

Bons estudos espero ter ajudado

Answer 2

$\mathsf{(-2-5)^2\cdot(\sqrt1)-2\cdot[-5\cdot(-3)\div\sqrt{-7+16}]}\\\\\mathsf{(-7)^2\cdot1-2\cdot[15\div\sqrt9]}\\\\\mathsf{49\cdot1-2\cdot[15\div3]}\\\\\mathsf{49-2\cdot5}\\\\\mathsf{49-10}\\\\\boxed{\boxed{\mathsf{39}}}$

Resposta: 39.

Bons estudos.
