Question

(ii) (-2)' * (-2)} * (-2) simplify​

Answer 1

Step-by-step explanation:

3 1/3 ÷ 5/3 - 1/10 of 2 ½ + 7/4

= (3 × 3 + 1)/3 ÷ 5/3 – 1/10 of (2 × 2 + 1)/2 + 7/4

= 10/3 ÷ 5/3 - 1/10 of 5/2 + 7/4

[‘of’ simplified]

= 10/3 × 3/5 – ½ × ½ + 7/4 [‘÷’ simplified]

= 2/1 - ¼ + 7/4 [‘×’ simplified]

= (2 × 4)/1 × 4) - (1 × 1)/4 × 1) + (7 × 1)/4 × 1)

= 8/4 - ¼ + 7/4

Answer 2

Correct question

Simplify

• { (-2) × (-2) } × (-2)

Solution

$\sf\pink{⟶}$ Solving these types of questions is always confusing. But I will tell a simple way to solve this question.

$\sf\green{⟶}$ According to BODMAS we have to solve the bracket first.

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {{(-2) × (-2)} × (-2)}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {{4} × (-2)}$

⠀

$\sf\purple{⟶}$ After solving the bracket we can solve the whole question easily.

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {(4) × (-2)}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {-8}$
