Answer:
A³ - 35A = A
Step-by-step explanation:
Given,
A =
⇒ A = 2[2(2)-2(2)] - 2[2(2)-2(2)] + 2[2(2)-2(2)]
⇒ A = 2[0] - 2[0] + 2[0]
⇒ A = 0
A³ =
⇒ A³ =
⇒ A³ =
⇒ A³ =
⇒A³ =
Evaluate the value of det,
⇒ A³ = 8(8(8)-8(8)) - 8(8(8)-8(8)) + 8(8(8)-8(8))
⇒ A³ = 8(0) - 8(0) + 8(0)
⇒ A³ = 0
now, evaluate '35A'
⇒ 35A = 35
⇒ 35A = 35(0) = 0
so, ∴ A³ - 35A = 0 - 0 = 0 = A
HOPE THIS WOULD BE HELPFUL FOR YOU
