Question 1196038
Please help me with this problem

Rationalize the denominator 

<a  rel=nofollow HREF="https://imgbb.com/"><img src="https://i.ibb.co/5vmS6zp/IMG-4270.jpg" alt="IMG-4270" border="0"></a>

<pre>{{{3/root(5, 8)}}} is the same as {{{3/matrix(2,1, " ", 8^(1/5))}}}

We then get: {{{highlight_green(matrix(1,10, (matrix(2,1, " ", 3 * 8^(4/5)))/matrix(2,1, " ", 8^(1/5) * 8^(4/5)), "=", (matrix(2,1, " ", 3 * 8^(4/5)))/matrix(2,1, " ", 8^(1/5 + 4/5)), "=", 3 * 8^(4/5)/8, ",", or, 3 * 8^(4/5 - 1), "=", 
highlight(matrix(2,1, " ", 3 * 8^(- 1/5)))))}}}

You didn't mention anything about NEGATIVE exponents being DISALLOWED!</pre>
