Question

how am I suppose to go about with coefficients/powers multiplying and dividing. I am not understanding in videos and he just writes them. doesnt seem like being added or subtracted I dont know what is happening to them. For example on a problem, he wrote, 6.626x10^-34J.S (3.00x10^8m/s/3.25x10^-2m= 6.12x10^-24 J/1 Photon. And I have no idea whats happening with the coefficients he doesnt mention what is ocurring with them ever.

  • Hi Ilene! For negative exponents, you just have to put minus/negative sign next to the exponent. Reyn commented 4 days ago
