Answer:
C. 5.43×10¹⁴
Step-by-step explanation:
Given the number 543 followed by 12zeros, this is written in figure as
543,000,000,000,000
To convert to scientific notation, first we will locate a decimal point at the end of the number as shown:
543,000,000,000,000.
Then we will shift the decimal point to the back until we reach the first digit of the number. Since the total number in the figure is equivalent to 15, it means the decimal point will be shifted to the back 14times.
This means that the power of 10 in out notation will be +14(because we move decimal backwards) ás shown:
543,000,000,000,000 = 5.43 × 10¹⁴
