20. Humans can distinguish up to 18,400,000
individual dots called pixels on a typical
computer display. Can a human distinguish
pixels on a same-sized HDTV with
2 x 106 pixels? Explain.

The answer is yes, because 2 × 10⁶ < 18,400,000, human can distinguish pixels on a same-sized HDTV.

Step-by-step explanation:

Step 1:

2⋅10⋅10⋅10⋅10⋅10⋅10 = 20⋅10⋅10⋅10⋅10⋅10 = 200⋅10⋅10⋅10⋅10 = 2,000⋅10⋅10⋅10 = 20,000⋅10⋅10 = 200,000⋅10 = 2,000,000

Step 2:

Because 2 × 10⁶ < 18,400,000, human can distinguish pixels on a same-sized HDTV.
