What is the simplest form of 6 radical 8 plus 8 radical 2
arsen [322]

Answer:

20\sqrt{2}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplify

\sqrt{8} = \sqrt{4(2)} = \sqrt{4} × \sqrt{2} = 2\sqrt{2}

Thus

6\sqrt{8} + 8\sqrt{2}

= 6(2\sqrt{2} ) + 8\sqrt{2}

= 12\sqrt{2} + 8\sqrt{2}

= 20\sqrt{2}

Select the correct answer.
svetlana [45]

Step-by-step explanation:

The over all order of the reaction with the rate law of rate=k[A][B] is 2 since the exponent for [A] is 1 and the exponent for [B] is 1 and 1+1=2.  

for example the order for the rate law rate=[A]²[B] is 3 since 2+1=3 and the order for a rate law of rate=[A]²[B]³ the order would be 5 since 2+3=5.

I hope this helps.  Let me know if anything is unclear.
