Answer:

Step-by-step explanation:

Given the expression $\frac{720,800}{x} = 7.208$ , we are to find the value of with powers of 10.

From the equation:

$\frac{720,800}{x} = 7.208$

cross multiply

$720,800 = 7.208x\\7.208x = 720,800$

divide both sides by 7.208

$\frac{7.208x}{7.208} = \frac{720,800}{7.208} \\x = 100,000$

express x in powers of 10

$x = 10 * 10 * 10 * 10* 10\\x = 10^5$

Similarly given the equation $\frac{720,800}{y} = 72.08$

From the equation:

$\frac{720,800}{x} = 72.08$

cross multiply

$720,800 = 72.08x\\72.08x = 720,800$

divide both sides by 7.208

$\frac{72.08x}{72.08} = \frac{720,800}{72.08} \\x = 10,000$

express x in powers of 10

$x = 10 * 10 * 10 * 10\\x = 10^4$

For the equation $\frac{720,800}{z} = 720.8$

From the equation:

$\frac{720,800}{z} = 720.8$

cross multiply

$720,800 = 720.8z\\720.8z = 720,800$

divide both sides by 7.208

$\frac{72.08z}{720.8} = \frac{720,800}{720.8} \\z = 1,000$

express x in powers of 10

$z = 10 * 10 * 10\\z = 10^3$
