Subtract 4.66\times10^{-5}-7.34\times10^{-7}
To subtract these two numbers, we can directly subtract their decimal parts while keeping the same exponential part.
The decimal subtraction is: 4.66 - 7.34 = -2.68.
Therefore, the result is -2.68 × 10^(-5).

To subtract numbers in scientific notation, you need to make sure that both numbers have the same exponent. In this case, we have:
4.66 × 10^(-5) - 7.34 × 10^(-7)
To make the exponents equal, we can convert the second number:
7.34 × 10^(-7) = 0.734 × 10^(-6)
Now both numbers have an exponent of -5, so we can subtract them directly:
4.66 × 10^(-5) - 0.734 × 10^(-6)
Next, we subtract the numbers in front of the exponent:
4.66 - 0.734 = 3.926
Finally, we keep the common exponent to get the final result:
3.926 × 10^(-5)
To subtract these two numbers written in scientific notation, we need to make sure that the exponents are the same.
Step 1: Let's convert the numbers into the same power of 10 by adjusting the exponents.
4.66 × 10^(-5) = 0.0000466 (since we moved the decimal to the left 5 places)
7.34 × 10^(-7) = 0.000000734 (since we moved the decimal to the left 7 places)
Step 2: Now that both numbers have the same exponent, we can subtract them.
0.0000466 - 0.000000734 = 0.000045866 (subtracting the numbers)
Step 3: Finally, we can convert the result into scientific notation.
0.000045866 = 4.5866 × 10^(-5) (since we moved the decimal to the right 5 places)
So, the subtraction of 4.66 × 10^(-5) - 7.34 × 10^(-7) is equal to 4.5866 × 10^(-5).
