Questions: Evaluate the expression when n=8 n(1-n)=[?]

Transcript text: Evaluate the expression when $\mathrm{n}=8$ \[ \mathrm{n}(1-\mathrm{n})=[?] \]

Solution

To evaluate the expression when $ n = 8 $, we need to substitute $ n $ with 8 in the given expression and then perform the arithmetic operations.

Step 1: Substitute $ n $ with 8

Given the expression $ n(1 - n) $, we substitute $ n $ with 8: \[ 8(1 - 8) \]

Step 2: Simplify the expression inside the parentheses

Calculate $ 1 - 8 $: \[ 1 - 8 = -7 \]

Step 3: Multiply the results

Multiply 8 by $-7$: \[ 8 \times (-7) = -56 \]

\[ \boxed{-56} \]
