    Exponents Laws
AI Thread Summary
The discussion focuses on verifying answers related to simplifying expressions using the laws of exponents. For the first problem, the participant simplifies (5x^3yz^2)^2(-3x^3y^4z) and arrives at -75x^9y^6z^5, which is confirmed as correct. In the second problem, they simplify 8a^-2b^3c^4/18a^5b^-3c to get 4b^6c^3/9a^7, which is also validated as correct. The participant expresses a need for assistance due to a lack of real-life support for these math problems. Overall, both answers provided are confirmed to be accurate.

Basically I don't know anyone in real life that can help me with this, so I need help checking to see if my answers are correct :)

PART A

7) Simplify (5x^3yz^2)^2(-3x^3y^4z)

My answer: -75x^9y^6z^5

8) Simplify the problem below using positive exponents only.

8a^-2b^3c^4
18a^5b^-3c

My Answer:
4b^6c^3
9a^7

Both correct.

I underlined your numerators there. :)
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Imaginary Pythagorus'

Thread 'Imaginary Pythagorus'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
