Evaluate the expression for k = 0, m = –7, and n = 20.2.

Question

Write your answer as a decimal or whole number.

km2n =

Answer 1

To evaluate the expression \( km^2n \) for \( k = 0 \), \( m = -7 \), and \( n = 20.2 \), we can follow these steps:

1. First, calculate \( m^2 \): \[ m^2 = (-7)^2 = 49 \]

2. Next, substitute \( k \), \( m^2 \), and \( n \) into the expression: \[ km^2n = 0 \cdot 49 \cdot 20.2 \]

3. Since \( k = 0 \), any expression multiplied by 0 is 0: \[ km^2n = 0 \]

Therefore, the evaluated expression is: \[ \boxed{0} \]
