1/x

0

1

ANSWER

1

EXPLANATION

We want to simplify:

Recall that:

We use this property of exponents to get:

Any non-zero number to the exponent of zero is 1.

Last option

Step-by-step explanation:

You need to remember the Negative exponent rule:

You also need to remember the Product ot poers property and the Quotient of powers property, which are:

And:

Therefore, you can rewrite the expression as following:

Applying the properties, you can simplify:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
