Question

Evaluate the expression for h = –8, j = –0.8, and k = –7.

Write your answer as a decimal or whole number.

hj2k =

Answer 1

To evaluate the expression \( hj^2k \) with the given values \( h = -8 \), \( j = -0.8 \), and \( k = -7 \), we follow these steps:

1. Calculate \( j^2 \):
\[
j^2 = (-0.8)^2 = 0.64
\]

2. Substitute \( h \), \( j^2 \), and \( k \) into the expression \( hj^2k \):
\[
hj^2k = (-8) \times (0.64) \times (-7)
\]

3. First, calculate \( (-8) \times (0.64) \):
\[
-8 \times 0.64 = -5.12
\]

4. Now, multiply the result by \( -7 \):
\[
-5.12 \times (-7) = 35.84
\]

Thus, the value of \( hj^2k \) is \(\boxed{35.84}\).
