What is 2 log x - logy - 2 log z written as a single logarithm?

Hitman42 [59]

Answer:

Log [x^2 / yz^2]

Step-by-step explanation:

2log(x) =log(x^2)

-log(y) = The minus sign means that you can divide it by first log(x^2)

-2log(z) =log(z^2), and the minus sign again means you can divide it by the first log(x^2)

So, the whole thing can be written like this:

Log(x^2) / [log(y)*log(z^2)], OR:

Log [x^2 / yz^2]

Simplify a^2-3a/a^3-8a^2+12a to lowest terms

svetoff [14.1K]

In order to simplify a fraction, we have to find a common factor in both numerator and denominator. So, let's start by factor the expressions completely: at the numerator we have

$a^2-3a = a(a-3)$

At the denominator we have

$a^3-8a^2+12a = a(a^2-8a+12) = a(a-2)(a-6)$

So, the fraction can be written as

$\dfrac{a(a-3)}{a(a-2)(a-6)}$

You can see that there is a factor $a$ in common, that can be simplified:

$\dfrac{a(a-3)}{a(a-2)(a-6)} = \dfrac{a-3}{(a-2)(a-6)}$
