Question

a) 2² + √81:9 b) 2 + √100:5-32 c)2-(√1-5-√16) d) 8²: (6-2-√√100) e) 12-[9²-(√64 +7-10)] 1) 2²:4+3 [√25-(3-2)]-7​

Answer 1

Resposta:

Explicação passo a passo:

A) 4+$\sqrt{9$=

4+3=7

B) 4+10:5-9=
4+2-9= -3

C) 10

D)

E)-64

F) 2³ : 4 +3 [√25 - 1] -7

2³ : 4 + 3 [ 5 - 1 ] - 7

2³: 4 + 3 x 4 -7

8 : 4+3x4-7 =

2 + 12 - 7=

14-7=

7
