Best ResponseYou've already chosen the best response.0Okay. sooo, this is really broad, but I don't understand negative exponents.... At all.

Best ResponseYou've already chosen the best response.5So you got some specific questions or do you want me or us to explain you negative exponents from scratch?

MetalPen

Best ResponseYou've already chosen the best response.0Ummmmmmm. Why does a negative exponent make a fraction? I don't understand the basic concept.

Best ResponseYou've already chosen the best response.1Negative exponents simply means this: \[a^{x} = {1 \over a^x}\]

Best ResponseYou've already chosen the best response.5yea slaaibak got it

MetalPen

Best ResponseYou've already chosen the best response.0Yes but why are they defined that way?

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5do you know \[a^x \times a^y= a^{x+y}\]

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5now say we want \[a^x \times a^y = 1\]

MetalPen

Best ResponseYou've already chosen the best response.0You'd made one negative!!! AHHH I GET IT!

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5so when we solve that we get \[a^{x+y}= 1 = a^0\]

Best ResponseYou've already chosen the best response.0So another thing, how do you deal with #s with exponents in a fraction?

slaaibak

Best ResponseYou've already chosen the best response.1Give an example please?

MetalPen

Best ResponseYou've already chosen the best response.0Ummmm. How do you make fractions with this equation thing?

Best ResponseYou've already chosen the best response.53 over 4 \[3 \over 4\]

slaaibak

Best ResponseYou've already chosen the best response.1Use this code: {1 over 2} would be \[{1 \over 2}\]

MetalPen

Best ResponseYou've already chosen the best response.0... Um can I just say it?

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5yea what is your doubt? i do not comprehend it

MetalPen

Best ResponseYou've already chosen the best response.0Okay so if you had y^5 times 2^3 over y^4 times x^2.

MetalPen

Best ResponseYou've already chosen the best response.0Or something to that effect.

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5\[ y^5 \times 2^3 \over y^4 \times x^2.\]

slaaibak

Best ResponseYou've already chosen the best response.1\[{ y^{5} * 2^3 \over y^4 * x^2}\]

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5is that your query?

slaaibak

Best ResponseYou've already chosen the best response.1You're faster than me xD

slaaibak

Best ResponseYou've already chosen the best response.1If there's multiplication, you can take y^5 and but it below the line, \[y^{5} = {1 \over y^5}\] You can immediately write 2^3 as 8. So now you have: \[{1 \over y^5} * {8 \over x^2 * y^4}\]

slaaibak

Best ResponseYou've already chosen the best response.1Then, you can multiply similar variables with eachother and add the powers. it becomes: \[8 \over y^9 * x^2\]

Best ResponseYou've already chosen the best response.0What are you talking about?

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5about the question you asked

slaaibak

Best ResponseYou've already chosen the best response.1I made a spelling mistake in my post.

MetalPen

Best ResponseYou've already chosen the best response.0Yeah but how did you get y^9?

MetalPen
 3 years ago
Best ResponseYou've already chosen the best response.0I know you have to add... Or subtract the exponents or something.

slaaibak

Best ResponseYou've already chosen the best response.1\[y^4 * y^5 = y^{5 + 4}\]

Best ResponseYou've already chosen the best response.5the main aim of such questions is to convert your negative exponents into positive by taking its reciprocal

MetalPen

Best ResponseYou've already chosen the best response.0Um one more thing. How would you get {1 over 9} % of 90. Or something like that.

MetalPen

Best ResponseYou've already chosen the best response.0Aw shoot. I messed up the thing.

Best ResponseYou've already chosen the best response.5percent is always divided by 100

Akshay_Budhkar
 3 years ago
Best ResponseYou've already chosen the best response.5so 1/9 percent is \[(1/9 ) \over 100 = 1\over900\]

Akshay_Budhkar

Best ResponseYou've already chosen the best response.5of 90 is 1/900 of 90.. of implies multiplication

Akshay_Budhkar
 3 years ago
Best ResponseYou've already chosen the best response.5so it is 1/900 times 90 = 90/900 = 1/10

MetalPen

Best ResponseYou've already chosen the best response.0That makes sense! Okay that's all! And I have to go. Thank you so much. ^.^
