AI Thread Summary

To solve the expression ksp = (3.42 x 10^-7) (6.84 x 10^-7)^2, first square the second term, resulting in (6.84 x 10^-7) x (6.84 x 10^-7) = 4.67 x 10^-13. Next, multiply this result by the first term: (3.42 x 10^-7) x (4.67 x 10^-13). When multiplying, combine the coefficients (3.42 x 4.67) and add the exponents (-7 + -13), leading to a final answer of 1.6 x 10^-19. Understanding the multiplication of coefficients and the addition of exponents is crucial for these calculations. Mastering these steps will enhance proficiency in solving similar chemistry-related math problems.

In the expression:

ksp = (3.42 x 10^-7) (6.84 x 10^-7)^2
= 1.6 x 10^-19

I don't understand how the final answer is found. Can someone show me a step by step? I'm attempting to understand how to do these types of questions! Any help is greatly appreciated!

You're having trouble multiplying the exponents? I have a feeling you didn't ask the entire question.

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

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...
