can you write any whole number as the sum of powers of 2 and only use each power once

can-8 be written in scientific notation?

Simplify (5.6x10^13)(7x10^-2)/2.45x10^6 I need some help 1.6 x10^6 if it's not correct would you please explain

My sister and I have a bet on my homework The length of a rectangle is 1.2 x10-4 kilometer. The width of the rectangle is 6.25x10^-5 kilometer. What is the area in square kilometers of this rectangle? 7.5x10-9 or 7.5x10^3

A system of equations are shown below -y+2x=4 2x-y= -4 if i solve separately it has infinite solutions but if i solve together there are no solutions is it infinite or no solution?

first find the [ace acid] (which is 0.0040~M) use Ka constant formula to solve for [H3o+] then use C1V1 = C2V2 where c1= [ace acid] = 0.004~M c2= [initial HCl] = 12M v1= (initial volume of HCl) = 0.01L and you have to solve for v2 i think this is right lo...

since everything is a 1:1 ratio, you know that [acetic acid] = [H3O+] forgot to add that..

wow i'm just forgetting every thing today: when you find v2, don't forget to minus the initial volume!!! =) (since they are asking how much is added) i got 29.80L
