Question

1. 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 2×100³ pixels? explain.

Explanation:

Step1: Calculate the number of pixels on the HDTV

First, calculate $2\times100^{3}$. Since $100^{3}=100\times100\times100 = 1000000$, then $2\times100^{3}=2\times1000000 = 2000000$.

Step2: Compare with human - distinguishing ability

We know that humans can distinguish up to 18400000 pixels. Since $2000000<18400000$.

Answer:

Yes, a human can distinguish pixels on a same - sized HDTV with $2\times100^{3}$ pixels because the number of pixels on the HDTV ($2000000$) is less than the maximum number of pixels ($18400000$) that humans can distinguish.
