Answer:

During the span of 9 days, the water level of lake decreased by 18 inches.      

Step-by-step explanation:

We are given the following information in the question:

For 8 hot days, the water level decreased in a lake at rate of 3 inches per day.

Then on day 9, there was a storm that increased the water level by 6 inches.

Total drop in water level in lake =

\text{Number of days}\times \text{Rate of drop in water level per day}\\= 8\times 3\text{inches per day}\\=24\text{ inches}

Expression for the change in the water level =

\text{Increase in water level in 9 days} - \text{Decrease in water level during 9 days}\\=6 - 24\\ = -24 + 6 = -18\text{ inches}

Hence, during the span of 9 days, the water level of lake decreased by 18 inches.

Norma-Jean [14]

Remember the laws of exponents:

\frac{a^n}{a^m}=a^{n-m}

Then:

\begin{gathered} \frac{3^{100}}{3^{99}}=3^{100-99} \\ =3^1 \\ =3 \end{gathered}

Therefore:

\frac{3^{100}}{3^{99}}=3
