Question
Express the number using the exponential notation: $512$
✓
Answer
In order to express $512$ in exponential notation, we should find the factors of $512$ by prime factorisation method, and then express $512$ as the product of its prime factors
$\therefore 512=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2=2^9$
Also,
$512=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2$
$=2^3 \times 2^3 \times 2^3$
$=8^3$
$\therefore 512=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2=2^9$
Also,
$512=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2$
$=2^3 \times 2^3 \times 2^3$
$=8^3$
