Answer:

Option (b) is correct.

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

Step-by-step explanation:

Given: (2^\frac{1}{4} )^4

We have too choose the correct simplification for the given statement.

Consider (2^\frac{1}{4} )^4

Using property of exponents, (a^m)^n=a^m\times a^m\times a^m\times ....\times (n\ times)

We have,

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

Again applying property of exponents  a^m\times a^m=a^{n+m}

We have,

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

Simplify, we have,

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

we get,

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

Thus, (2^\frac{1}{4} )^4=2

Option (b) is correct.

(2^{1/4})^4=2^{1/4}.2^{1/4}.2^{1/4}.2^{1/4}=2^{1/4+1/4+1/4+1/4}=2^{4/4}=2

There you use these properties:

1) definition of the power=> (2^{1/4})^4 =2^{1/4}.2^{1/4}.2^{1/4}.2^1/4}

2) multiplication of powers with the same base:

a^n.a^m.a^p.a^q=a^{n+m+p+q}

3) sum of fractions: 1/4 +1/4 +1/4 +1/4 = 4/4

4) simplification of fractions: 4/4 = 1
