How is this written in an expanded version?

Yuri [45]

Powers distribute over multiplications:

$(ab)^c = a^c\cdot b^c$

So, you have

$(3k^5)^2 = 3^2 \cdot (k^5)^2$

Now, $3^2$ is simply 9.

As for $(k^5)^2$ , we have to use the rule

$(a^b)^c = a^{bc}$

to get

$(k^5)^2=k^{5\cdot 2}=k^{10}$

So, the final answer is

$(3k^5)^2 =9k^{10}$

360 arrangements of 4 bridesmaids from her 6 closest friends are possible !

<u>Step-by-step explanation:</u>

Here we have , For a wedding the bride must select 4 bridesmaids from her 6 closest friends and must arrange them in order for the ceremony. We need to find How many arrangements of 4 bridesmaids from her 6 closest friends. Let's find out:

We know that formula for permutation is given by :

⇒ $nP_r = \dfrac{n!}{(n-r)!}$

According to question we have following parameters as : n = 6 , r = 4

⇒ $6P_4 = \dfrac{6!}{(6-4)!}$

⇒ $6P_4 = \dfrac{6!}{(2)!}$

⇒ $6P_4 = \frac{6(5)(4)(3)2!}{(2)!}$

⇒ $6P_4 =360$

Therefore , 360 arrangements of 4 bridesmaids from her 6 closest friends are possible !
