Write log8 3 as a logarithm of base 5.

1 answer:

7 0

The answer is <span>2) (log5)3/(log5)8
</span>
We will use the change-of-base formula: $log_a(x)= \frac{log_b(x)}{log_b(a)}$

So, if we want to write <span>log8 3 as a logarithm of base 5, </span> in these example a = 8, x = 3, b = 5:
$log_8(3)= \frac{log_5(3)}{log_5(8)}$

Suppose you have 5 riders and 5 horses, and you want to pair them off so that every rider is assigned one horse (and no horse is

maw [93]

There are 120 ways in which 5 riders and 5 horses can be arranged.

We have,

5 riders and 5 horses,

Now,

We know that,

Now,

Using the arrangement formula of Permutation,

i.e.

The total number of ways $^nN_r = \frac{n!}{(n-r)!}$ ,

So,

For n = 5,

And,

r = 5

As we have,

n = r,

So,

Now,

Using the above-mentioned formula of arrangement,

i.e.

The total number of ways $^nN_r = \frac{n!}{(n-r)!}$ ,

Now,

Substituting values,

We get,

$^5N_5 = \frac{5!}{(5-5)!}$

We get,

The total number of ways of arrangement = 5! = 5 × 4 × 3 × 2 × 1 = 120,

So,

There are 120 ways to arrange horses for riders.

Hence we can say that there are 120 ways in which 5 riders and 5 horses can be arranged.
