Calculated Answer

560

Step by Step Solution

In order to solve problem, you must evaluate n₀ * n₁ * n₃ * n₀ * n₂.

n₀ =	2
n₁ =	7
n₂ =	4
n₃ =	5

n₀ * n₁ * n₃ * n₀ * n₂
Evaluate n₀ * n₁ = 14
14 * n₃ * n₀ * n₂
Evaluate n₀ * n₂ = 8
14 * n₃ * 8
Evaluate n₃ * 8 = 40
14 * 40
Evaluate 14 * 40 = 560
560
The answer to the problem and the result of n₀ * n₁ * n₃ * n₀ * n₂ is 560
