Subtract 4.66x10^-5-7.34x10^-7
To subtract 4.66x10^-5 from 7.34x10^-7, we need to align the exponents and then subtract the coefficients.
First, let's align the exponents:
4.66x10^-5 can be expressed as 0.0000466
7.34x10^-7 can be expressed as 0.000000734
Now, subtract the coefficients:
0.0000466 - 0.000000734 = 0.000045866
Therefore, the result of subtracting 4.66x10^-5 from 7.34x10^-7 is 0.000045866.
To subtract these two numbers in scientific notation, we need to make sure their exponents are the same. In this case, we can rewrite both numbers in terms of 10^-5.
4.66x10^-5 - 7.34x10^-7
To rewrite 7.34x10^-7 in terms of 10^-5, we multiply it by 10^2.
7.34x10^-7 * 10^2 = 7.34x10^-7 * 100 = 7.34x10^-5
Now that both numbers have the same exponent (10^-5), we can subtract them directly:
4.66x10^-5 - 7.34x10^-5
To subtract these numbers, we subtract their coefficients while keeping the common exponent:
4.66 - 7.34 = -2.68
Therefore, the result is -2.68x10^-5.
To subtract these two numbers written in scientific notation, we need to make sure that the exponents of the numbers are the same.
Let's consider the given numbers:
4.66 x 10^-5 - 7.34 x 10^-7
The exponents are different: -5 and -7. We want to adjust the exponents so that they are the same.
To do this, we can either increase the exponent of 7.34 x 10^-7 or decrease the exponent of 4.66 x 10^-5.
Since -7 is smaller than -5, it is easier to adjust the exponent of 7.34 x 10^-7.
To increase the exponent of 7.34 x 10^-7 from -7 to -5, we need to divide it by 10 twice (or multiply it by 10 twice in the denominator of a fraction).
Now, let's calculate the subtraction:
4.66 x 10^-5 - 7.34 x 10^-7 = 4.66 x 10^-5 - (7.34 x 10^-7) / (10^-7) (10^-7)
= 4.66 x 10^-5 - (7.34 x 10^-7) / 10^-14
= 4.66 x 10^-5 - 7.34 x 10^-21.
Since the exponents are the same, we can directly subtract the coefficient of the numbers:
4.66 x 10^-5 - 7.34 x 10^-21 = (4.66 - 0.00000000000000000000734) x 10^-5.
= 4.65999999999999992 x 10^-5.
Therefore, the result is approximately 4.66 x 10^-5.
