Question

Resolva as expressões:

a) 20:(2+2)+3.2-5 =

b)5³-[3+√25.(8.2.3)] =​

Answer 1

A) $20 \div (2 + 2)+3 \times 2 - 5 \\ 20 \div 4 + 3 \times 2 - 5 \\ 5 + 3 \times 2 - 5 \\ 3 \times 2 \\ 6$

B) ${5}^{3} - (3 + \sqrt{25} \times (8 \times 2 \times 3)) \\ 125 - (3 + \sqrt{25} \times (8 \times 2 \times 3)) \\ 125 - (3 + 5 \times (8 \times 2 \times 3)) \\ 125 - (3 + 5 \times 48) \\ 125 - (3 + 240) \\ 125 - 243 \\ - 118$

Essas são as respostas, até mais! =)
