Using a property of Logarithms Demonstrate that

Jlenok [28]

Answer:

Dividing logarithms is not the same as dividing the arguments of a logarithm.

Step-by-step explanation:

1) If we divide two logarithms then we'll find a value. This is not the same as dividing two arguments of the same base logarithms.

For example:

$\\ \frac{ln3}{ln2}=1.58\neq ln \left ( \frac{3}{2} \right )= ln3-ln2=0.405$

Then

$\\ \frac{lnx}{lny}\neq ln \left ( \frac{x}{y} \right )= lnx-lny$

2) Completing the table below to show it clearly:

Please help me . factor. X^2-13x+40

Ainat [17]

Consider the factors of 40: ±1, ±4, ±10, ±5, ±8 ... ±5 and ±8 can be manipulated to fit your factorization.

(x - 8)(x - 5) works. -8 - 5 = -13, which is what you need in the middle, and -8*-5 gives you a positive 40.
