simplify 2^{log_{4}(x)}

Solution

simplify

2^{l o g_{4} (x)}

Solution

x

Solution steps

2^{l o g_{4} (x)}

Factor the number:

4 = 2^{2}

= 2^{l o g_{2^{2}} (x)}

Apply log rule:

lo g_{a^{b}} (x) = \frac{1}{b} lo g_{a} (x), a > 0

lo g_{2^{2}} (x) = \frac{1}{2} lo g_{2} (x)

= 2^{\frac{1}{2} l o g_{2} (x)}

Apply exponent rule:

a^{b c} = (a^{b})^{c}, a \geq 0

2^{\frac{1}{2} l o g_{2} (x)} = (2^{l o g_{2} (x)})^{\frac{1}{2}}

= (2^{l o g_{2} (x)})^{\frac{1}{2}}

Apply log rule:

a^{l o g_{a} (b)} = b

2^{l o g_{2} (x)} = x

= x^{\frac{1}{2}}

Apply exponent rule:

a^{\frac{1}{2}} = a

x^{\frac{1}{2}} = x

= x
