Question

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

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:
\[
\boxed{0}
\]
