PLEASEE HELPP....Simplify the expression using properties of exponents.

Aleks04 [339]

Answer:

D

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{n} }{a^{m} }$ = $\frac{1}{a^{(m-n)} }$

Given

$\frac{25a^{-5}b^{-8} }{5a^{4}b }$

= $\frac{25}{5}$ × $\frac{a^{-5} }{a^{4} }$ × $\frac{b^{-8} }{b^{1} }$

= 5 × $\frac{1}{a^{(4-(-5))} }$ × $\frac{1}{b^{(1-(-8))} }$

= 5 × $\frac{1}{a^{9} }$ × $\frac{1}{b^{9} }$

= $\frac{5}{a^{9}b^{9} }$ → D

If a phone charges 3% every five minutes then how long will it take for the phone to charge 100%

postnew [5]

To find out how long it will take a phone to charge 100% if it charges 3% every 5 minutes, you have to put it in a fraction.

3/5

3 is the percent charged and 5 is the time.

You have to find out what 100 divided by 3 is. The answer is 33.3.

So,

3/5 times 33.3 is equal to 99.9/166.5.

It will take 166.5 minutes for the phone to charge to about 100%.

hope it helps.
