how to transform the quantity of the fifth root of x to the seventh power, to the third power into an expression with a rational

Maurinko [17]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-----------------------------\\\\
\sqrt[5]{(x^7)^3}\implies \sqrt[5]{x^{7\cdot 3}}\implies \sqrt[5]{x^{21}}\implies x^{\cfrac{}{}\frac{21}{5}}$

Charlie weighs 9 pounds more than his little brother. If together they weigh 99 pounds what is the algebraic equation for Charli

Afina-wow [57]

To set up the equation you would take x and add the nine pounds that Charlie weighs more than his brother and the set that equal to 99. Your equation would be X+9=99. If you wanted to take it a step further and solve the equation you would distract 9 from both sides which means that x=90
