(3a-1/6a)^3 write in expansions
Answers
Step-by-step explanation:
Given 36 ÷ 6 + 3
According to BODMAS rule we have operate division first then we have to do addition
Therefore 36 ÷ 6 + 3 = 6 + 3 = 9
2. 24 + 15 ÷ 3
Solution:
Given 24 + 15 ÷ 3
According to BODMAS rule we have operate division first then we have to do addition
Therefore 24 + 15 ÷ 3 = 24 + 5 = 29
3. 120 – 20 ÷ 4
Solution:
Given 120 – 20 ÷ 4
According to BODMAS rule we have operate division first then we have to do multiplication
Therefore 120 – 20 ÷ 4 = 120 – 5 = 115
4. 32 – (3 × 5) + 4
Solution:
Given 32 – (3 × 5) + 4
According to BODMAS rule we have operate in brackets first then we have move to addition and subtraction.
Therefore 32 – (3 × 5) + 4 = 32 – 15 + 4
= 32 – 11 = 21
5. 3 – (5 – 6 ÷ 3)
Solution:
Given 3 – (5 – 6 ÷ 3)
According to BODMAS rule we have operate in brackets first then we have move to subtraction.
Therefore 3 – (5 – 6 ÷ 3) = 3 – (5 – 2)
= 3 –3 = 0
6. 21 – 12 ÷ 3 × 2
Solution:
Given 21 – 12 ÷ 3 × 2
According to BODMAS rule we have perform division first then multiplication and addition.
Therefore, 21 – 12 ÷ 3 × 2 = 21 – 4 × 2
= 21 – 8 = 13
7. 16 + 8 ÷ 4 – 2 × 3
Solution:
Given 16 + 8 ÷ 4 – 2 × 3
According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.
Therefore, 16 + 8 ÷ 4 – 2 × 3 = 16 + 2 – 2 × 3
= 16 + 2 – 6
= 18 -6
= 12
8. 28 – 5 × 6 + 2
Solution:
Given 28 – 5 × 6 + 2
According to BODMAS rule we have perform multiplication first then followed by addition and subtraction.
Therefore, 28 – 5 × 6 + 2 = 28 – 30 +2
= 28 – 28 = 0
9. (-20) × (-1) + (-28) ÷ 7
Solution:
Given (-20) × (-1) + (-28) ÷ 7
According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.
Therefore, (-20) × (-1) + (-28) ÷ 7 = (-20) × (-1) – 6
= 20 – 6 = 16
10. (-2) + (-8) ÷ (-4)
Solution:
Given (-2) + (-8) ÷ (-4)
According to BODMAS rule we have perform division first then followed by addition and subtraction.
Therefore, (-2) + (-8) ÷ (-4) = (-2) + 2
=0
11. (-15) + 4 ÷ (5 – 3)
Solution:
Given (-15) + 4 ÷ (5 – 3)
According to BODMAS rule we have perform division first then followed by addition and subtraction.
Therefore, (-15) + 4 ÷ (5 – 3) = (-15) + 4 ÷ 2
= -15 + 2
= -13
12. (-40) × (-1) + (-28) ÷ 7
Solution:
Given (-40) × (-1) + (-28) ÷ 7
According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.
(-40) × (-1) + (-28) ÷ 7 = (-40) × (-1) – 4
= 40 – 4
= 36
13. (-3) + (-8) ÷ (-4) -2 × (-2)
Solution:
Given (-3) + (-8) ÷ (-4) -2 × (-2)
According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.
(-3) + (-8) ÷ (-4) -2 × (-2) = -3 + 2 -2 × (-2)
= -3 + 2 + 4
= 6 – 3
=3
14. (-3) × (-4) ÷ (-2) + (-1)
Solution:
Given (-3) × (-4) ÷ (-2) + (-1)
According to BODMAS rule we have perform division first then followed by multiplication, addition and subtraction.
(-3) × (-4) ÷ (-2) + (-1) = -3 × 2 -1
= – 6 – 1
= -1
