Answer:

B

Step-by-step explanation:

Using the rule of exponents

a^{\frac{m}{n} } ⇔ \sqrt[n]{a^{m} }

Given

f(x) = 16^{x}, then when x = \frac{1}{2}

f(\frac{1}{2} ) = 16^{\frac{1}{2} } = \sqrt[2]{16} = 4

agasfer [191]

Answer:

Pie= 3.14

Step-by-step explanation:

Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
