Learn it Break a number into prime factors with a factor tree, then use exponents to show repeated primes: $2 \times 2 \times 2 = 2^3$.
Example: Write 360 as a product of primes using exponents.
- $360 = 36 \times 10 = (4 \times 9) \times (2 \times 5)$.
- $= 2 \times 2 \times 3 \times 3 \times 2 \times 5$.
- $360 = 2^3 \times 3^2 \times 5$.
