$\frac{1}{2^\frac{x}{50}}=$	A. \(0,5^{0,02x}\)
B. \(0,5^{0,002x}\)
C. \(2^{0,02x}\)
D. \(2^{\frac{50}x}\)
E. \(2^{-\frac{50}x}\)

1^ste manier :
$\frac{1}{2^\frac{x}{50}}=\frac{1}{2^\frac{x}{50}}=\left(\frac{1}{2}\right)^\frac{x}{50}=0,5^\frac{x}{50}=0,5^{0,02x}$
2^de manier :
$\frac{1}{2^\frac{x}{50}}=2^{-\frac{x}{50}}=2^{-0,02x}=\left(2^{-1}\right)^{0,02x}=0,5^{0,02x}$
