Question

Please help me simplify 20z/sqrt(z^13).

Answer 1

20z/sqrt((z^12)(z))
s0
20z/z^6(sqrt(z))
20/z^5(sqrt(z)

Answer 2

Thanks you, what does it mean in the second line where it says s0?

Answer 3

sorry i want to write: so

Answer 4

Oh, ok lol.

Answer 5

:)

Answer 6

Thanks you!

Answer 7

your welcome

Answer 8

\[ \frac{20z}{\sqrt{z^{13}} } \\
\frac{20z}{\sqrt{z^{12}}\sqrt{z}}\\
\frac{20z}{z^{6}\sqrt{z}}\\
\]
notice the z divided by sqr(z) is sqr(z)

if you use exponents:
\[ \frac{z}{z^\frac{1}{2}}= z^{1-\frac{1}{2}}= z^\frac{1}{2}=\sqrt{z} \]

your problem becomes
\[ \frac{20 \sqrt{z}}{z^6} \]
which can be re-written a number of ways...

Answer 9

Hmmm, ok.

Answer 10

@phi I am a little confused. This question is from a multiple choice worksheet, and both your answer and sara17's answers are options. Which one should I use? Is one further simplified then the other?
