Answer 1

We have,

$\quad \frac{4 \times 21.76}{2.154 \times {10}^{ - 22} \times 6.023 \times {10}^{23} } \\ \\ \\ = \frac{4 \times 21.76}{2.154 \times 6.023 \times {10}^{(23 - 22)} } \\ \\ \\ = \frac{4 \times 21.76}{2.154 \times 6.023 \times 10} \\ \\ \\ = \frac{4 \times 21.76}{21.54 \times 6.023} \\ \\ \\ = \frac{4 \times \cancel{21.76} \: {}^{10.88} }{_{10.77} \: \cancel{21.54} \times 6.023} \\ \\ \\ = \frac{4 \times 1088 \times 1000}{6023 \times 1077} \\ \\ \\ = \bf \quad 0.671$
