Question

1. $\frac{7.85\times10^{24}}{6.02\times10^{23}}$

Explanation:

Step1: Divide the coefficients

$\frac{7.85}{6.02}\approx1.304$

Step2: Divide the powers of 10

Using the rule $\frac{a^m}{a^n}=a^{m - n}$, we have $\frac{10^{24}}{10^{23}}=10^{24 - 23}=10^1$

Step3: Multiply the results

$1.304\times10^1 = 13.04$

Answer:

$13.04$
