Rewrite in simplest radical form, thx :)

Aleks [24]

Answer:

The answer is

$\sqrt[3]{ {x}^{2} }$

Step-by-step explanation:

$\frac{ {x}^{ \frac{5}{6} } }{ {x}^{ \frac{1}{6} } }$

Since they have the same base and are dividing we can use the rules of indices

That's

subtract the exponents

So we have

${x}^{ \frac{5}{6} - \frac{1}{6} }$

${x}^{ \frac{4}{6} }$

$= {x}^{ \frac{2}{3} }$

Rewriting it in radical form

We have the final answer as

$\sqrt[3]{ {x}^{2} }$

Hope this helps you

Factor then solve.<br>1.81 - 4x²=0<br>2. 4s² + 9 = 12s

elena-14-01-66 [18.8K]

$1.\\81-4x^2=0\\\\9^2-(2x)^2=0\\\\(9-2x)(9+2x)=0\iff9-2x=0\ \vee\ 9+2x=0\\\\-2x=-9\ \vee\ 2x=-9\\\\x=4.5\ \vee\ x=-4.5$

=============================================================

$2.\\4s^2+9=12s\\\\4s^2-12s+9=0\\\\(2s)^2-2\cdot2s\cdot3+3^2=0\\\\(2s-3)^2=0\\\\(2s-3)(2s-3)=0\iff2s-3=0\\\\2s=3\\\\s=1.5$
