Multiply both the top and the bottom by (4-3i) to eliminate i in the denominator:
10(4-3i)/(4+3i)(4-3i)=(40-30i)/[4²-(3i)²]=(40-30i)/25
reduce: (8-6i)/5
a=8, b=5, c=6, d=5
Answer:
The logarithmic function modeled by the given table:
f(x) = log₃x
Step-by-step explanation:
Given Table:
x f(x)
9 2
27 3
81 4
We can see that x increases as powers of 3. And f(x) is the power.
We assume that f(x) = log₃x
Checking using the table:
for x = 9
f(x) = log₃9 = 2
for x = 27
f(x) = log₃27 = 3
for x = 81
f(x) = log₃81 = 4
Hence proved.
