Expressed in simplified radical form what is the value of √r-√16r when r=2

Ket [755]

Answer:

- 3 $\sqrt{2}$

Step-by-step explanation:

using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

simplifying $\sqrt{16r}$ when r = 2

= $\sqrt{32}$

= $\sqrt{16(2)}$

= $\sqrt{16}$ × $\sqrt{2}$ = 4 $\sqrt{2}$ , hence

$\sqrt{2}$ - 4 $\sqrt{2}$ = - 3 $\sqrt{2}$

Find the sum of 7/13 and 11/26.

timofeeve [1]

Answer:

The sum of 7/13 and 11/26 is 25/26.

Step-by-step explanation:

First off you find the LCM (Least Common Multiple) between the denominators which are 13 and 26 in this case. The LCM between 13 and 26 would be 26. You then change 13 to the denominator of 26. 13x2 is 26 so whatever you do to one side or one part, you have to do to the other. Now, you will multiply 7x2 to get 14. Your final fractions are 14/26 and 11/26. When you add 14/26 and 11/26, you get 25/26. Hope this helps! :)
