subtract 4.66\times 10^(-5)-7.34\times 10^(-7)
To subtract these numbers, we need to make sure they have the same exponent.
First, let's express both numbers in scientific notation:
4.66 × 10^(-5) = 0.0000466
7.34 × 10^(-7) = 0.000000734
Now, we can subtract them:
0.0000466 - 0.000000734 = 0.000045866
To subtract the given numbers in scientific notation, follow these steps:
Step 1: Make sure both numbers have the same exponent.
In this case, we can rewrite the numbers as:
4.66 × 10^(-5)
7.34 × 10^(-7)
Step 2: Subtract the mantissas (the decimal parts).
4.66 - 7.34 = -2.68
Step 3: Keep the same exponent (10^(-5)).
The final result is:
-2.68 × 10^(-5)
To subtract these two numbers expressed in scientific notation, we need to have the same power of 10. Let's rewrite the numbers so that they have the same exponent:
4.66 × 10^(-5) = 0.0000466 × 10^0
7.34 × 10^(-7) = 0.000000734 × 10^0
Now that the exponents are the same, we can subtract the numbers:
0.0000466 × 10^0 - 0.000000734 × 10^0
To subtract, we simply subtract the decimal parts and keep the exponent the same:
0.0000466 - 0.000000734 = 0.000045866
Therefore, the result is 0.000045866 × 10^0 or 4.5866 × 10^(-5).
