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:

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

Could you please help me?

Answer:

x = 31

Step-by-step explanation:

AC=BD

3x+7 = 131-x

Subtract 7 from both sides

3x = 124-x

Add x to 3x

4x = 124

Divide by 4

x = 31

Check:

3(31)+7 = 131 - 31

Mulitply 3 times 31 / subtract 131 and 31

93+7 = 100

Add 93 to 7

100 = 100
