Answer 2

Answer:

$3^\frac{7}{10}$    or      $\sqrt[10]{3^7}$

Step-by-step explanation:

$\left(\sqrt{3}\right)\left(\sqrt[5]{3}\right)=\sqrt[10]{3^7}\quad$

(√3)($\sqrt[5]{3}$) = √3 · $\sqrt[5]{3}$

{√3 = $3^{\frac{1}{2}}$}                 {radical rule: $\sqrt{x}=x^1^/^2$}

$\sqrt3$$\sqrt[5]{3}$ =  $3^{\frac{1}{2}}$ · $\sqrt[5]{3}$

{$\sqrt[5]{3}$ = $3^{\frac{1}{5}}$}                  {radical rule: $\sqrt[n]{x} = x^1^/^n$}

 $3^{\frac{1}{2}}$ · $\sqrt[5]{3}$ =   $3^{\frac{1}{2}}$ · $3^{\frac{1}{5}}$     {exponent rule:  $a^x*a^y=a^x^+^y$}

                (1/2 + 1/5 = 5/10 + 2/10 = 7/10)

              $=3^\frac{7}{10}$        {opposite of radical rule: $\sqrt[n]{x} = x^1^/^n$ ;  $x^\frac{a}{b}=\sqrt[b]{x^a}$}

             = $\sqrt[10]{3^7}$

so, the simplified version of this equation can either be written as:

$3^\frac{7}{10}$    or      $\sqrt[10]{3^7}$

hope this helps!!

(I can't clearly see the last option, but if it's either of these, then it's correct)
