Hello, I hope someone can help me out a bit..
I'm doing some exercises and I fail at understanding 1/[(5*10^-3)(0,01*10^-6)
I do the maths:
(5*10^-3)(0,01*10^-6 = (5000 * 0,01)*10^-9 = 50 * 10^-9, right? ***edit: My mistake was resolving the first bracet alone first
Now it's 1/50*10^-9 but what is that 1/ ??? ***0,05 not 50***
The answer is 2*10^10 but I don't know how :S
50*10^-9 m= 0,000 000 05
So 1/000 000 05 = 20 000 000
And 20 000 000 to me is 2x 10^7 since I took the decimal 2 and "moved the coma" 7 times to get to 20 000 000
I need a little help please!
edit: guess I need a slap next time I resolve a bracet first lol
