Question

300-(90+70)+(86-46) 90/(10*9)/(9/9) 91/13*7 84/(14*3) Помогите плиз

Answer 1

1) 300-(90+70)+(86-46) =

300-160+132 = 172

2) 90/(10*9)/(9/9) =

90/90/1 = 1

3) 91/13*7 =

7*7 = 49

4) 84/(14*3) =

84/42 = 2

Answer 2

300-(90+70)+(86-46)=300-160=140+40=180 91/13*7=91/13=7*7=49 84/(14*3)=14*3=42 84/42=2

Answer 3

Let's solve these math expressions step by step:

1. 300 - (90 + 70) + (86 - 46) = 300 - 160 + 40 = 180

2. 90 / (10 * 9) / (9 / 9) = 90 / 90 / 1 = 1

3. 91 / 13 * 7 = (91 / 13) * 7 = 7 * 7 = 49

4. 84 / (14 * 3) = 84 / 42 = 2

Therefore, the answers are:

1. 180
2. 1
3. 49
4. 2
