subtract 4.66x10^-5 - 7.34x10^-7
To subtract the two numbers given in scientific notation, you need to make sure that the exponents are the same.
First, rewrite 4.66x10^-5 as 0.0000466 in standard decimal form.
Then, rewrite 7.34x10^-7 as 0.000000734 in standard decimal form.
Now that the exponents are the same, you can subtract the two numbers:
0.0000466 - 0.000000734 = 0.000045866
To subtract 4.66x10^-5 from 7.34x10^-7, we need to ensure that the exponents are the same.
Let's convert both numbers to have the same exponent:
4.66x10^-5 can be rewritten as 0.0000466x10^0
7.34x10^-7 can be rewritten as 0.000000734x10^0
Now that we have them both in the form 0.xxxx x 10^0, we can subtract them:
0.0000466x10^0 - 0.000000734x10^0 = 0.000045866x10^0
Since the exponent is 0, we can remove the scientific notation:
0.000045866 x 10^0 = 0.000045866
To subtract two numbers written in scientific notation, first, make sure the exponents have the same value. In this case, both numbers are written to the power of -5, so no conversion is necessary.
The subtraction is carried out as follows:
1. Subtract the coefficients: 4.66 - 7.34 = -2.68.
2. Leave the exponent unchanged.
Therefore, the result is -2.68 x 10^-5.
