Question

6 $\frac{6.25\times10^{6}}{12.5\times10^{-8}}$

Explanation:

Step1: Divide the coefficients

Divide 6.25 by 12.5.
$6.25\div12.5 = 0.5$

Step2: Divide the powers of 10

Use the rule $\frac{a^m}{a^n}=a^{m - n}$. So, $\frac{10^{6}}{10^{- 8}}=10^{6-(-8)}=10^{14}$.

Step3: Combine the results

Multiply the result of the coefficient - division and the power - of - 10 division. $0.5\times10^{14}$.

Step4: Convert to proper scientific notation

Move the decimal point one place to the right to get a number between 1 and 10. So, $0.5\times10^{14}=5\times10^{13}$.

Answer:

$5\times 10^{13}$
