Evaluate (0.55 - 0.5)/sqrt(0.5*0.5/400)

2.0

Step by step

  1. 2.0 = \frac{1}{20 \sqrt{\frac{1}{1600}}}

    Multiply: 0.5·0.5(1/400) = 1/1600.

  2. \frac{1}{20 \sqrt{\frac{1}{1600}}} = \frac{1}{20} \cdot 40

    Power: 1/(√(1/1600)) = 40.

  3. \frac{1}{20} \cdot 40 = 2

    Multiply: (1/20)·40 = 2.
