I like your video's very much. Yet, one thing I miss is the approach of the problems. I can follow your way, but in advance I have no clue. I'm 64 years of age now, and it's been half a century ago that I tried to / did solve those problems. So in an equation containing, say 4^x, you should announce we're going to aim for logs (maybe not always, but at least most of the times I can recall. I can continue, but I won't. You catch my drift, right?
Greetings from Roland, Venray, the Netherlands.
thank. bravo!
my answer: 64(10^98) or 6.4(10^99)
tricky math problem,
It would be better: 6,4 x 10^99 instead of 6 point 4
Why 6,4 rather than 6.4? I have never seen that format in sci notation.
@@dalphonhamilton9980That may depend on the country. If the point is (vertically) down, that’s OK, but in the video, it’s rather in the middle, that could cause a little misunderstanding. The point there can mean multiplication. (We use 5,76 rather than 5.76) Thanks. 😊
@@szentp6912 Ah. Thank you. I was unaware of that.

I Thank U too. Nice video indeed.
64×100⁴⁹.
64*10⁹⁸ or 6.4*10⁹⁹
4⁵² * 25⁴⁹ = 2¹⁰⁴ * 5⁹⁸ = 2⁶ * 2⁹⁸ * 5⁹⁸ = 64 * 10⁹⁸
For scientific notation, 1 ≤ a < 10 or a = 0 .
