Final answer:
To express numbers in scientific notation, move the decimal point left to create a number between 1 and 10, then multiply by 10 raised to the number of places the decimal was moved.
Step-by-step explanation:
To express the numbers 4350, 12,010, and 29,000,000 in scientific notation, we need to rewrite them as the product of a number between 1 and 10 and a power of 10.
- (a) 4,350 is written as 4.35 × 103 because the decimal point is moved 3 places to the left.
- (b) 12,010 is written as 1.201 × 104 because the decimal point is moved 4 places to the left.
- (c) 29,000,000 is written as 2.9 × 107 because the decimal point is moved 7 places to the left.
