What is the completely factored form of t4 − 16?

Mashcka [7]

we know that

A difference of squares problem can be factored as follows:

$a^{2}-b^{2} =(a+b)(a-b)$

in this problem we have

$t^{4}-16$

Applying difference of squares

$t^{4}-16=(t^{2}-4)( t^{2}+4)$

the term

$(t^{2}-4)=(t+2)(t-2)$

substitute

$(t^{2}-4)( t^{2}+4)=(t+2)(t-2)( t^{2}+4)$

therefore

<u>the answer is</u>

$(t+2)(t-2)( t^{2}+4)$

A water tank can be filled by an inlet pipe in 6 6 hours. it takes 4 4 times as long for the outlet pipe to empty the tank. how

enot [183]

To fill:
6 hours = 1 tank
1 hour = 1/6 tank

To drain:
It takes 4 times as long, therefore 4 x 6 = 24
24 hours = 1 tank
1hour = 1/24 tank

If both pipes are open
1 hour = 1/6 - 1/24 = 1/8 tank
1/8 tank = 1 hour
8/8 tank = 1 x 8 hour
1full tank = 8 hours
