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
1/ 243
Answer:
d = (R+3)(M)
Step-by-step explanation:

Add 3 both sides
d/M = R+3
Multiply M both sides
d = (R+3)(M)
Hope this helps!
