Subtract 4.66 x 10^-5 - 7.34 x 10^-7 (1 point)

answered
To subtract these numbers, we need to have the same exponent for the 10.
Let's write both numbers with the same exponent (we'll use -5):
4.66 x 10^-5 - 7.34 x 10^-7
= 4.66 x 10^-5 - 0.0734 x 10^-5 (we move the decimal point two places to the left in 7.34)
Now that the exponents are the same, we can subtract the numbers in front:
= (4.66 - 0.0734) x 10^-5
= 4.5866 x 10^-5
Therefore, 4.66 x 10^-5 - 7.34 x 10^-7 = 4.5866 x 10^-5

To subtract 4.66 x 10^-5 from 7.34 x 10^-7, you need to make sure that the exponents are the same. In this case, the first number has an exponent of -5, while the second number has an exponent of -7.
To make the exponents the same, we can rewrite 7.34 x 10^-7 as 0.0734 x 10^-5. Now that the exponents are the same, we can subtract the numbers:
4.66 x 10^-5 - 0.0734 x 10^-5 = (4.66 - 0.0734) x 10^-5
Calculating the subtraction in the brackets gives us:
4.66 - 0.0734 = 4.5866
So, the final answer is 4.5866 x 10^-5.

To subtract two numbers written in scientific notation, you need to ensure that their exponents are the same.
In this case, the exponents are already the same (both are negative).
So you can subtract the numbers directly.
4.66 x 10^-5 - 7.34 x 10^-7
To subtract, simply subtract the coefficients (the numbers before the "x 10^"):
(4.66 - 7.34) x 10^-5
= -2.68 x 10^-5
Therefore, the answer is -2.68 x 10^-5.
