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 $-7$ : $8 \times (-7) = -56$

$\boxed{-56}$
