1x10153 times 999999999 is 999999999x10153. Normalizing that, you get 9.999999999x10161.
It equals 285
If you mean: -4+3+2s = 15 then s = 8
That sum is 84. Since it's only one number, its mean is also 84. If those numbers were simply listed, without being added, then their mean would be 16.8 .
This looks like the commonly used shortcut for scientific notation. 1e20 or 1e+20 is the same as 1 x 1020.
1e+09 is equal to that of 1 billion.
It does nothing! It is a number.
1e+ is the number of zeros for example 10 is 1e+1 it have only 1 zeros 1eX is the size of the 1e+ example is that 1e+1000 is 1eX3 the number of zeros in 1e+ 1e^ is a large like 1e+10(1e+100000000000) same as the 1eX for the + 1e^1 is 1eX10 or 1e+100billion 1e- 1e/
The prefixes according to SI are: {| |- | yotta 1E+24 zetta 1E+21 exa 1E+18 peta 1E+15 tera 1E+12 giga 1E+09 mega 1000000 kilo 1000 hecto 100 deca 10 (none) 1 deci 0,10 centi 0,01 milli0,001 micro 1,00E-06 nano 1,00E-09 pico 1,00E-12 femto 1,00E-15 atto 1,00E-18 zepto 1,00E-21 yocto 1,00E-24 |}
If you mean a reaction of AgNO3 + Na(s) ==> NaNO3 + Ag(s), there would be ONE electron transferred.Ag^+ + 1e- ==> Ag(s) Reduction reaction Na(s) ==> Na^+ + 1e- Oxidation reaction
If you mean: 7 plus blank = 15 then it is 7+8 = 15
1e-17 = -16

1x10153 times 999999999 is 999999999x10153. Normalizing that, you get 9.999999999x10161.
A million billion in scientific notation is 1e+15 or 1 x 10^15
1e-24 = -23
It equals 285
