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

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