Final answer:
The division of the given scientific notation numbers results in 1.6×105.
Step-by-step explanation:
To solve the problem, we need to divide the numbers in scientific notation and then express the result in scientific notation as well. We start by dividing the coefficients (1.248÷7.8) and then subtracting the exponents (-2 - (-7)), as per the laws of exponents for division.
The coefficient division gives us approximately 1.6 (since 1.248÷7.8 ≈1.6). The exponent subtraction gives us -2 - (-7) which simplifies to -2 + 7 = 5. Hence the result in scientific notation is 1.6×105.
Looking at the answer options, the correct choice is none of the above since the result is 1.6×105.
