Question

What is the simplified form of 15 times x to the fifth power over 20 times y to the sixth power times the fraction 6 times y to the fourth power over 5 times x-squared ?

Answer 1

\[15x^6/20y^5 * 6y^2/5x^4\]

Answer 2

@phi @tkhunny Hey guys, can yall help me with this, I've been stuck on it for like 20 minutes and my lesson really isn't of any help. Thanks

Answer 3

Well, your words don't match your notation. The exponents are switched in both fractions.

Answer 4

Oh woops, well the proper one is the equation itself.

Answer 5

The answer choices are:
\[9x^2/10y^3\]
\[9x^3/10y^2\]
\[10x^3/9y^2\]
\[10x^2/9y^3\]

Answer 9

What is the equation written properly?

Answer 10

nvm i got it

Answer 11

It's the first reply, right under the original question posted.

Answer 12

The exponents did not match each variable.

Answer 13

What would the first step be?

Answer 15

You're welcome.

Answer 16

15x^6/20y^5∗6y^2/5x^4

Rearrange \(\dfrac{15\cdot 6}{20\cdot 5}\cdot\dfrac{x^{6}}{x^{4}}\cdot\dfrac{y^{2}}{y^{6}}\)

Does that look any easier?

Answer 17

wouldn't consider what I said rudeness, simply looking for a straight forward answer in a timely manner. AndI'm sorry, but not much @tkhunny I got the answer from the other guy's link, but if you walk me through how you do it, it would be greatly appreciated.

Answer 18

its a concept called "common factors", and something called an inverse property.

not too sure where the disconnect would be without guiding you thru it with leading questions tho.

Answer 19

the variable parts are the simplest .... x^k and x^n have xs in common

the number parts would have to be factored of simplified in some manner to see what they have in common
