Answer:
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)
