We can write options a, b, c as,

\cdots \longrightarrow \text{Option A: $\sqrt[12]{32}=(2^5)^\frac{1}{12}=2^{\frac{5}{12}}$}

\cdots \longrightarrow \text{Option B: $\sqrt[12]{2}=2^{\frac{1}{12}}$}

\cdots \longrightarrow \text{Option C: $\sqrt{2}=2^{\frac{1}{2}}$}

First, let's learn about the properties of exponents. These are crucial to solving the problem.

Real exponents

\cdots \longrightarrow \boxed{(a^{m})^{n}=a^{mn}}

\cdots \longrightarrow \boxed{a^{m} \cdot a^{n}=a^{m+n}}

Rational exponents

\cdots \longrightarrow \boxed{\text{${a}^{\frac{m}{n}}=\sqrt[n]{a^{m}}$ for an integer $n \geq 2$}}

Calculation

\boxed{\begin{aligned}\sqrt[3]{2} \cdot 2^{-\frac{1}{3}} \cdot \sqrt[12]{32}&=2^{\frac{1}{3}} \cdot 2^{-\frac{1}{3}} \cdot(2^5)^{\frac{1}{12}}\\\\&=2^{\frac{1}{3}} \cdot 2^{-\frac{1}{3}} \cdot 2^{\frac{5}{12}}\\\\&=2^{\frac{1}{3}-\frac{1}{3}+\frac{5}{12}}\\\\&=2^{\frac{5}{12}}.\end{aligned}}

Hence, option A is correct.

Question :-

Find the product of  \sqrt[3]{2}  \times (2)^{  \large - \frac{1}{3}}  \times  \sqrt[12]{32}  \\ .

Answer :-

  • 2 {}^{ \large \frac{5}{12} }

Step by step explanation :-

If we have to solve the question first we have to know the exponent form.

Required Exponent form,

\rm\bullet \: {x {}^{a}  \times x {}^{b}  = x {}^{a + b} }

\rm\bullet \: {(x {}^{a})^{b} = x {}^{a \times b}  }

\rm\bullet \: {x {}^{  \large\frac{a}{b} } =  \sqrt[b]{x {}^{a} }  }

Solving the expression,

\rm:\longmapsto{ \sqrt[3]{2} \times 2 {}^{ \large  - \frac{ 1}{3} }   \times  \sqrt[12]{32} } \:  \:   \:  \:  \:  \\  \\ \rm:\longmapsto{2 {}^{ \large \frac{1}{3} } \times 2 {}^{ \large -  \frac{1}{ 3 } } \times (2 {}^{5} )  {}^{ \large  \frac{1}{12} }  }  \:  \:  \: \\  \\\rm:\longmapsto{2 {}^{  \large\frac{1}{3} }  \times 2 {}^{ \large -  \frac{1}{3} } \times 2 {}^{  \large\frac{5}{12} }  } \:  \:  \:  \:  \:  \:  \:   \:  \\  \\ \rm:\longmapsto{2 {}^{  \large\frac{1}{3} -  \frac{1}{3}  +  \frac{5}{12}  } } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \rm:\longmapsto \red{ 2{}^{ \large \frac{5}{12} } } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:
