Calculate.
Write your answer in scientific notation.

3 x 10^-12.

Step-by-step explanation:

2.7 / 9 = 0.3 and 10^-7 / 10^4 = 10^-11.

So this gives 0.3 x 10^-11

But scientific form requires that the first number is 1 - 10 so the answer is:

3 x 10^-12.

(We multiply the first number (0.3) by 10, then to maintain equality we divide the second part (10^-11) by 10)

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.
