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:

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

Softa [21]

Answer:

It takes 70 minutes for 9 team members (painting 60 sq ft per minute) to paint a 4200 sq ft wall.

Step-by-step explanation:

According to the situation the calculation is shown below:-

= $\frac{4800}{20}$

= 240 sq ft each member of the team in 36 minutes

= $\frac{240}{36}$

= 6.67 sq ft each member of the team within 1 minute

$= 6.67\times 9$

= 60 sq ft for every 9 team members in one minute

= $\frac{4200}{60}$

= 70 minutes (or 1 hour and 10 minutes)

Hence, the 70 minutes is taken for 9 team members
