Question

how do you write 72,000 in scientific notation? $square \times 10^{square}$

Explanation:

Step1: Identify coefficient (1≤c<10)

To get a number between 1 and 10 from 72,000, we divide by 10 until we reach 7.2.
$\frac{72000}{10^4} = 7.2$

Step2: Find the exponent of 10

We divided 72,000 by $10^4$ to get 7.2, so the exponent is 4.

Answer:

$7.2 \times 10^4$
