Answer:
754
Step-by-step explanation:
If the number in the one's place is 5 or greater, the number is rounded up to the next ten. If the number is less than 5, the number gets rounded down.
754 is the answer because it rounds down to 750 as it is, but if 1 was added to it, it'd be 755 which would round up to 760.
Answer:
7.8*10^7
1.0 * 10^4
Now divide 7.8/1.0 and the power goes up to be subtracted
=7.8 * 10^(7-4)
= 7.8 * 10^3
