Question

a) 5² : ( 5 +1 -1)+ 4 x 2 = b) (3 +1)² +2 x 5 - 10⁰ = c) 3²: ( 4 – 1) + 3 x 2²

Answer 1

Resposta:

Explicação passo-a-passo:

a) 5² : ( 5 +1 -1)+ 4 x 2 =

5²=25

(5+1-1) = 5

4x2=8

25/ 5+8

25/13 = 1,9223

b) (3 +1)² +2 x 5 - 10⁰ =

(3+1)²=16

2x5=10

10⁰=1

16+10+1=27

c) 3²: ( 4 – 1) + 3 x 2²

9/ (3) + 3 x 4

9/ 3 + 12

9/ 15

3/5 = 0,6
