text: garden snail travels at approximately 0.000083 miles per sound which of these is 0.000083 written in? scientific notations? a. 0.83 s 10-4 or b 8.3 x 10-5. please show your work you really don't need a lot of work here since you have 0.000 something you must have 10 to the minus power. if you had 0.5 for example it would be 5*10^(-1), but if you had 0.05 it would be 5*10^(-2), so the power depends on the number of digits immediately after "."  in your case 0.000083 has 6 digits after first zero so it will be 0.000083= 83*10^(-6) , but you now that 83=8.3*10=8.3*10^1  83*10^(-6)= (8.3)*10^1*10^(-6)= (8.3)*10^(1-6)= 8.3*10^(-5)   therefore the answer is b).
