Question

Verify: m x (n x p) = (m x n) x p if m = 3; n = (- 5) and p = 4 with steps

Answer 1

Step-by-step explanation:

3×(-5×4) = (3×-5)×4

3×(-20)= (-15)×4

3×-20= -15×4

-60= -60

Answer 2

Given :

• m = 3
• n = (-5)
• p = 4

To find :

• to verify - m x (n x p) = (m x n) x p

Solution :

Here,

• m = 3
• n = (-5)
• p = 4

And,

• LHS = m x (n x p)
• RHS = (m x n) x p

-------------------

⇒ Let's verify!

$\rightarrow \sf m \times (n \times p) = (m \times n) \times p$

→ 3 (-5 × 4) = (3 × (-5) × 4

→ 3 (-20) = (-15) × 4

→ 3 × (-20) = (-15) × 4

→ -60 = -60

• Therefore, L.H.S = R.H.S. And hence, verified!!!
