Subtract 4.66×10^−5−7.34×10^−7 (1 point)
4.66×10^−5 - 7.34×10^−7 can be simplified by subtracting the coefficients and keeping the same base (10) raised to the exponent:
(4.66 - 0.0734) × 10^(-5 - (-7))
= 4.5866 × 10^2
= 458.66
To subtract numbers expressed in scientific notation, we need to make sure that the exponents are the same. Let's rewrite both numbers with the same exponent.
4.66 × 10^(-5) can be rewritten as 0.0000466 × 10^0
7.34 × 10^(-7) can be rewritten as 0.000000734 × 10^0
Now we can subtract the two numbers:
0.0000466 × 10^0 - 0.000000734 × 10^0 = 0.0000466 - 0.000000734
Subtracting the decimal numbers, we get:
= 0.000045866
Therefore, subtracting 4.66 × 10^(-5) by 7.34 × 10^(-7) equals 0.000045866 or 4.5866 × 10^(-5).
To subtract 4.66 × 10^(-5) - 7.34 × 10^(-7), we need to perform the subtraction operation between these two numbers.
When subtracting numbers in scientific notation, it is important to ensure that both numbers have the same power of 10. In this case, 4.66 × 10^(-5) and 7.34 × 10^(-7) have different powers of 10.
To make them have the same power of 10, we can convert 7.34 × 10^(-7) to scientific notation with a power of 10 equal to -5.
To do this, we multiply 7.34 × 10^(-7) by 10^2 (which means multiplying by 100):
(7.34 × 10^(-7)) × (10^2) = 7.34 × 10^(-7+2) = 7.34 × 10^(-5)
Now that both numbers have the same power of 10 (-5), we can perform the subtraction:
4.66 × 10^(-5) - 7.34 × 10^(-7) = (4.66 - 7.34) × 10^(-5)
Calculating the subtraction of the coefficients:
4.66 - 7.34 = -2.68
Therefore, the result is: -2.68 × 10^(-5)
