Answer:

Option 1 - 64^{\frac{1}{4}}=2\sqrt[4]{4}

Step-by-step explanation:

Given : Expression 64 Superscript one-fourth i.e. 64^{\frac{1}{4}}

To find : Which is equivalent to expression ?

Solution :

Step 1 - Write the expression,

64^{\frac{1}{4}}

Step 2 - Factor the term 64,

=(2\times 2\times 2\times 2\times 2\times 2)^{\frac{1}{4}}

=(2^6)^{\frac{1}{4}}

=(2^4\cdot 2^2)^{\frac{1}{4}}

Step 3 - Apply exponent rule, (x^a)^{\frac{1}{b}}=x^{\frac{a}{b}}

=(2)^{\frac{4}{4}}\cdot (2)^{\frac{2}{4}}

=(2)^{1}\cdot (2)^{\frac{2}{4}}

=2\cdot 4^{\frac{1}{4}}

=2\sqrt[4]{4}

Therefore, 64^{\frac{1}{4}}=2\sqrt[4]{4}

So, Option 1 is correct.
