In order to subtract numbers written in scientific notation, the exponents must be the same.
We can rewrite the numbers as:
4.66×10^(-5) - 7.34×10^(-7)
To make the exponents match, we can rewrite 7.34×10^(-7) as:
0.0734×10^(-5)
Now we have:
4.66×10^(-5) - 0.0734×10^(-5)
To subtract these numbers, we just subtract the coefficients (the numbers before the multiplication sign) and keep the same exponent:
(4.66 - 0.0734) × 10^(-5)
4.5866 × 10^(-5)
We can rewrite the numbers as:
4.66×10^(-5) - 7.34×10^(-7)
To make the exponents match, we can rewrite 7.34×10^(-7) as:
0.0734×10^(-5)
Now we have:
4.66×10^(-5) - 0.0734×10^(-5)
To subtract these numbers, we just subtract the coefficients (the numbers before the multiplication sign) and keep the same exponent:
(4.66 - 0.0734) × 10^(-5)

To find the increase in the national debt over the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.
$2.9617×10^13 - $3.98×10^11
First, let's rewrite the numbers so that the exponents match:
$29.617×10^12 - $0.398×10^12
Now, we subtract the coefficients and keep the same exponent:
($29.617 - $0.398) × 10^12
$29.219 × 10^12
Therefore, the national debt increased by $29.219 × 10^12 in the 50-year period.
$2.9617×10^13 - $3.98×10^11

To find the difference between the sizes of the hydrogen and oxygen atoms, we subtract their sizes:
1.2×10^(-10) - 0.000000000152
In order to subtract these values, we need to rewrite them in the same units.
1.2×10^(-10) is already in scientific notation, so no further conversion is needed.
0.000000000152 can be rewritten in scientific notation as:
1.52×10^(-10)
Now we can subtract the values:
1.2×10^(-10) - 1.52×10^(-10)
To subtract these values, we subtract the coefficients and keep the same exponent:
(1.2 - 1.52) × 10^(-10)
Therefore, the difference between the sizes of the hydrogen and oxygen atoms is -0.32 × 10^(-10) in scientific notation.
1.2×10^(-10) - 0.000000000152

To determine which blood component has a bigger diameter, we compare the given diameters of the platelet and red blood cell:
Platelet diameter: 2.33×10^(-6) m
Red blood cell diameter: 0.0000075 m
Comparing the two values, we see that the red blood cell has a larger diameter than a platelet.
To determine the difference in their diameters, we subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33×10^(-6) m
To perform the subtraction, we need to express both values in the same format.
2.33×10^(-6) m can be rewritten as 0.00000233 m.
Now, we can simply subtract the values:
0.0000075 m - 0.00000233 m = 0.00000517 m
Therefore, the red blood cell has a bigger diameter than a platelet by 0.00000517 m.
From the given options, the correct answer is: A red blood cell has a bigger diameter than a platelet by 5.17×10^−6 m.

To find the difference in population between China and India, we subtract the population of India from the population of China:
China's population: 1.45×10^9
India's population: 1,400,000,000
To perform the subtraction, we need to convert the population of India to scientific notation:
India's population: 1.4×10^9
Now, we can subtract the values:
1.45×10^9 - 1.4×10^9
To subtract these values, we subtract the coefficients:
(1.45 - 1.4) × 10^9 = 0.05 × 10^9
Therefore, there are 0.05 × 10^9 more people living in China than in India.
