Express 15 x^1/3y^1/5 using a radical
k0ka [10]
In short, to convert two fractions to have the same denominator, we simply multiply one by the denominator of the other, so in this case, we'll multiply 1/3 by 5, top and bottom, and 1/5 by 3, top and bottom, thus

\bf a^{\frac{ n}{ m}} \implies  \sqrt[ m]{a^ n} 
\qquad \qquad
\sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}}\\\\
-------------------------------

\bf \cfrac{15x^{\frac{1}{3}}}{y^{\frac{1}{5}}}\qquad 
\begin{cases}
\frac{1}{3}=\frac{1\cdot 5}{3\cdot 5}\\
\qquad \frac{5}{15}\\\\
\frac{1}{5}=\frac{1\cdot 3}{5\cdot 3}\\
\qquad \frac{3}{15}
\end{cases}\implies \cfrac{15x^{\frac{5}{15}}}{y^{\frac{3}{15}}}\implies 15\cdot \cfrac{x^{\frac{5}{15}}}{y^{\frac{3}{15}}}\implies 15\cdot \cfrac{\sqrt[15]{x^5}}{\sqrt[15]{y^3}}
\\\\\\
15\sqrt[15]{\frac{x^5}{y^3}}

Answer:

The correct option is (b).

Step-by-step explanation:

We need to find the equivalent to -2(4-3x)+(5x-2)

Using the associative property,

-2(4-3x) = -2(4)+2(3x)

= -8+6x

So,

-2(4-3x)+(5x-2) = -8+6x +5x-2

taking like terms together,

-2(4-3x)+(5x-2) = 6x+5x-8-2

= 11x-10

The equivalent expression is equal to (11x-10).
