You can multiply in any order if it's all multiplication.
So you can do (4.5*6)*(10^-8*10^-4)
which equals 27*10^-12

Written in scientific notation is 2.7 * 10^-11 (Since you moved decimal one back, you don't have to move it again in the exponent, hence it becomes 10^-11)
D. is the answer

Im confused on this one !
Alex787 [66]

I believe that it would be the first one. They are looking for the distance from the y-axis, so the x value doesnt matter. 6 is 6 units away from the y-axis, and -6 is also 6 units away from the y-axis. Hope I helped!
