To subtract 4.66×10^−5 from 7.34×10^−7, you need to subtract the numbers separately and then subtract the exponents.
First, subtract the numbers: 7.34×10^−7 - 4.66×10^−5 = 7.34 - 4.66 = 2.68
Next, subtract the exponents: 10^(-7) - 10^(-5) = 10^(-7-(-5)) = 10^(-7+5) = 10^(-2) = 1/100 = 0.01
Therefore, the final answer is 2.68×10^(-2), or 2.68 times 10 to the power of negative 2.
thats wrong
Apologies for the mistake in my previous response. Let's correct it.
To subtract 4.66×10^−5 from 7.34×10^−7, you need to subtract the numbers and keep the same exponent.
7.34×10^−7 - 4.66×10^−5 = 7.34×10^(-7-(-5)) - 4.66×10^(-5-(-5)) = 7.34×10^(-7+5) - 4.66×10^0
Since 10^0 equals 1, the expression simplifies to:
7.34×10^(-2) - 4.66×1 = 7.34×10^(-2) - 4.66
Therefore, the correct answer is 7.34×10^(-2) - 4.66.
To subtract numbers in scientific notation, you first need to make sure that the exponents (the superscripts) are the same. In this case, both numbers have exponents of -5.
Then, you can simply subtract the decimals.
Start by subtracting the decimal part:
4.66 - 7.34 = -2.68
Next, write down the common exponent (-5) and express the result in scientific notation:
-2.68 × 10^(-5)
So the answer is -2.68 × 10^(-5).
To subtract 4.66×10^−5−7.34×10^−7, you need to subtract the numerical parts and keep the exponent the same.
4.66×10^−5 - 7.34×10^−7
First, subtract the numerical parts: 4.66 - 7.34 = -2.68
Next, keep the exponent the same: 10^−5
Therefore, the result is -2.68×10^−5.
