Show that for any positive numbers a and b with a ≠ 1 and b ≠ 1, loga(b) ∙ logb(a) = 1.

elena55 [62]

Answer:

logₓ(y) = $\frac{\log(y)}{\log(x)}$

$\frac{\log(b)}{\log(a)}\times\frac{\log(a)}{\log(b)}$

= 1

Step-by-step explanation:

Data provided:

a ≠ 1 and b ≠ 1

To prove $\log_a(b).\log_b(a)=1$

RHS = 1

LHS = $\log_a(b).\log_b(a)$

Now,

We have the property of the log function as:

logₓ(y) = $\frac{\log(y)}{\log(x)}$

applying the above property on the LHS side to solve LHS, we get

LHS = $\frac{\log(b)}{\log(a)}\times\frac{\log(a)}{\log(b)}$

LHS = 1

Since,

LHS = 1 is equal to the RHS = 1

Hence, proved that $\log_a(b).\log_b(a)=1$

Which expression can be simplified as 1/18n? (n2)9. (n^-9)-2. (n^-6)-3. (n^-6)-3. (n-3)^6

mariarad [96]

Answer:

$\frac{1}{n^{18}} = (n^{-3})^6$

Step-by-step explanation:

Given

$\frac{1}{n^{18}}$

Required

Determine its equivalent

$\frac{1}{n^{18}}$

Express 18 as 3 * 6

$\frac{1}{n^{18}} = \frac{1}{(n^{3})^6}$

This can be rewritten as:

$\frac{1}{n^{18}} = (\frac{1}{n^{3}})^6$

Apply the following law of indices:'

$\frac{1}{a^b} = a^{-b}$

$\frac{1}{n^{18}} = (n^{-3})^6$

Hence;

<em>(d) is correct</em>
