What is the simplest form of the quotient 4 square root 810 over 4 square root 2

Len [333]

Answer:

$3\sqrt[4]{5}$

Step-by-step explanation:

Given: $\frac{\sqrt[4]{810} }{\sqrt[4]{2} }$

Top and bottom has fourth root. so we take fourth root in common

$\sqrt[4]{\frac{810}{2} }$

When we divide 810 by 2. we will get 405

$\sqrt[4]{405}$

Now we simplify the fourth root

405 can be written as 3*3*3*3*5

$\sqrt[4]{3*3*3*3*5}$

$3\sqrt[4]{5}$

spayn [35]

Answer:

$\large\boxed{32\ is\ 90\%\ of\ 35\dfrac{5}{9}}$

Step-by-step explanation:

<h3>METHOD 1:</h3>

$\begin{array}{ccc}32&-&90\%\\\\x&-&100\%\end{array}\qquad\text{cross multiply}\\\\\\90x=3200\qquad\text{divide both sides by 90}\\\\x=\dfrac{3200}{90}\\\\x=\dfrac{320}{9}\\\\x=35\dfrac{5}{9}$

<h3>METHOD 2:</h3>

$\begin{array}{cccc}32&-&90\%&\text{divide both sides by 9}\\\\\dfrac{32}{9}&-&10\%\end{array}\\\\\\90\%+10\%=100\%\to32+\dfrac{32}{9}=32+3\dfrac{5}{9}=35\dfrac{5}{9}$
