Answer:
112 = 7x
16 = x x = 16
x = 16
Explanations:The given rquation is:
Step 1: Cross multiply the equations. That is 28 multiplies 4 and 7 multiplies x:
Step 2: Divide both sides by 7
Answer:
The error is in step 3. You cannot use a property of logarithms to prove that same property.
Step-by-step explanation:
Here we the proof of the quotient rule as
If Logₐx = M and Logₐy = N
Then x = and y =
x ÷ y = ÷
=
Take log of both sides we get
Logₐ(x÷y) = Logₐ
Logₐ(x÷y) =M-N logₐa
Logₐ(x÷y) =M-N
∴Logₐ(x÷y) = Logₐx - Logₐy
