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 n^4 divided by n1/2

agasfer [191]

Given:

Consider the expression is

$\dfrac{n^4}{n^{\frac{1}{2}}}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\dfrac{n^4}{n^{\frac{1}{2}}}$

Using the properties of exponents, we get

$=n^{4-\frac{1}{2}}$ $\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]$

$=n^{\frac{8-1}{2}}$

$=n^{\frac{7}{2}}$

Therefore, the simplified form of the given expression is $n^{\frac{7}{2}}$ .
