Respuesta :

so this exponent of 1/2 mean square-root of 64 what equal 

64^(1/2) = (8^2)^(1/2) = 8^((1/2)*2) = 8^(2/2) = 8

hope helped 

Answer:

8

Step-by-step explanation:

We are asked to find the value of the given exponential expression [tex]64^{\frac{1}{2}[/tex].

Using exponent property [tex]a^{\frac{m}{n}}=\sqrt[n]{a^m}[/tex], we can write our given expression as:

[tex]64^{\frac{1}{2}=\sqrt[2]{64^1}[/tex]

[tex]64^{\frac{1}{2}=\sqrt[2]{64}[/tex]

We can rewrite [tex]64\text{ as }8^2[/tex].

[tex]64^{\frac{1}{2}=\sqrt[2]{8^2}[/tex]

Using exponent property [tex]\sqrt[n]{a^n}=a[/tex], we can write our given expression as:

[tex]64^{\frac{1}{2}}=8[/tex]

Therefore, the value of our given exponential expression is 8.
