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

Solution

simplify

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

Solution

x^{2}

Solution steps

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

Factor the number:

4 = 2^{2}

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

Apply exponent rule:

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

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

Apply exponent rule:

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

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

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

Apply log rule:

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

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

= x^{2}
