When finding GCF and LCM, it is is easiest to start by factoring

81=3*3*3*3
99=3*3*11

GCF, group the common ones
3*3 is common
GCF is 9

LCM
group common ones that include all
3*3*3*3*11=891

GCF=9
LCM=891

Answer:

1 / 3^5

1/ 243

Step-by-step explanation:

3^4 ÷ 3^9

We know that a^b ÷ a^c = a^ ( b-c)

3 ^ ( 4-9)

3^ -5

We can rewrite this as a^-b = 1/ a^b

1 / 3^5

We know that 3^5 = 243

I need help on this math problem.

OLEGan [10]

B: (0, a)

C should have the same y value as B

D: (a,0)

C should have the same x value as D

So point C is (a,a)

Since point A is on the origin, its point is (0,0)

You use the slope formula and plug in point A and C:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{a-0}{a-0}$

$m=\frac{a}{a}$

m = 1

So the value that belongs in the green box is 1
