Question

write 80 as a product of prime factors.
$80 = \square$

Explanation:

Step1: Divide by smallest prime (2)

$80 = 2 \times 40$

Step2: Divide 40 by 2

$40 = 2 \times 20$, so $80 = 2 \times 2 \times 20$

Step3: Divide 20 by 2

$20 = 2 \times 10$, so $80 = 2 \times 2 \times 2 \times 10$

Step4: Divide 10 by 2

$10 = 2 \times 5$, so $80 = 2 \times 2 \times 2 \times 2 \times 5$

Step5: Write in exponent form

$80 = 2^4 \times 5$

Answer:

$2^4 \times 5$ (or $2 \times 2 \times 2 \times 2 \times 5$)
