Wifi waves travel through space as rapid, data encoded pulses or waves. ... Wifi occupies the radio frequency band of the electromagnetic spectrum between actual radio waves and microwaves (used to listen to the game, and cook your dinner, respectively).

Here's how you simplify those. The rule for raising an exponent to an exponent is that you multiply them. The rule for dividing exponents with the same base is that you subtract the denomonator from the numerator. So let's simplify the first one, which is actually the most confusing.
$( \frac{ p^{5} }{ p^{-3} q^{-4} } )^{ \frac{1}{4} }$
Multiplying the exponents you get:
$( \frac{ p^{ \frac{5}{4} } }{ p^{- \frac{3}{4} } q^{-1} })$
Subtracting the denominator from the numerator between the common base of p you get this:
$\frac{ p^{ \frac{5}{4}- (-\frac{3}{4}) } }{ q^{-1} }$
Doing that math gives you
$\frac{ p^{2} }{ \frac{1}{q} }$ which equals $\frac{ p^{2} }{1} * \frac{q}{1}$ which is $p^{2}q$ , or the third one down.

The next one:
$( \frac{ p^{2} q^{7} }{ q^{4} } )^{ \frac{1}{2} }$
simplifies to:
$\frac{p* q^{ \frac{7}{2} } }{ q^{2} }$
and subtracting the power of the denominator from the power of the numerator gives you:
$p q^{ \frac{3}{2} }$ , which is the last choice.
$( p^{6}q \frac{3}{2})^{ \frac{1}{3} }$
simplifies to:
$( p^{6* \frac{1}{3} } )( q^{ \frac{3}{2}* \frac{1}{3} })$
which simplifies very nicely to:
$p^{2}q^{ \frac{1}{2} }$ , which is the first choice. The other one is found by process of elimination!

A store has clearance items that have been marked down by 40%. They are having a sale, advertising an additional 45% off clearan

Olegator [25]

Answer:

$P_2 = (1-0.45) *0.6 P_o =0.55*0.60 P_o=0.33 P_o$

So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:

$\% Change = \frac{|0.33P_o -P_o|}{P_o}*100 =67\%$

Step-by-step explanation:

First we have a first discount of 40% so then using this condition and assuming that $P_o$ represent the initial price, the price after the first discount $P_1$ is given by:

$P_1 = (1-0.4) P_o =0.6P_o$

That means 60% of the original value.

Now we have another discount of 45% for the 60% reamining after a 2 discount so let's $P_2$ represent the price after the second disccount we can can express this price in terms of $P_1$ or $P_o$ liek this:

$P_2 = (1-0.45) P_1=0.55 P_1$

$P_2 = (1-0.45) *0.6 P_o =0.55*0.60 P_o=0.33 P_o$

So the discount is 33% and we are paying 67% of the value. The reason is given by the relative change:

$\% Change = \frac{|0.33P_o -P_o|}{P_o}*100 =67\%$
