5 x 2 = 10 halves
first you forget the 2 is there. then you go : 1/10 x 1/10 x 1/10 x 1/10 x 1/10 x 1/10 = b now make b a 2. 2 x 10 -6 is 0.000002.
262,144 = (2 x 10^5) + (6 x 10^4) + (2 x 10^3) + (1 x 10^2) + (4 x 10^1) + (4 x 10^0)
1 x 10, 2 x 5, 5 x 2, 10 x 1.
e^2-x = 10^x-2 let take the natural log of both sides we have 2-x=ln ( 10^(x-2) 2-x=x-2(ln 10) 4-2x=ln10 -2x=ln10-4 x= -1/2[(ln10)+4)]
5 x 2 = 10 halves
2/9 = 0.2222222222 = 2 x 10^-1 + 2 x 10^-2 + 2 x 10^-3 + 2 x 10^-4 + 2 x 10^-5 + 2 x 10^-6 + 2 x 10^-7 + 2 x 10^-8 + 2 x 10^-9 + 2 x 10^-10
2 x 25 5 x 10 2 x 5 x 5
10 x 2 = 20
2 x 10-5
-2
Well, honey, 50 goes into 110 two times with a remainder of 10. Simple math, darling. Just divide and conquer.
10 x 8 + 3 x 2 ie 86
2 x 10^1 x 1 x 10^5 = 2 x 10^6
(6 x 10^7) + (7 x 10^6) + (1 x 10^5) + (0 x 10^4) + (2 x 10^3) + (2 x 10^2) + (0 x 10^1) + (0 x 10^0)
262,144 = (2 x 10^5) + (6 x 10^4) + (2 x 10^3) + (1 x 10^2) + (4 x 10^1) + (4 x 10^0)
There are ten quarters. (2 x 4 + 2 = 10)
