Subtract 4.66×10^−5−7.34×10^−7 (1 point)
Responses
To subtract the given numbers in scientific notation, we need to make sure the exponents are the same.
4.66 × 10^(-5) - 7.34 × 10^(-7) = (4.66 × 10^(-5)) - (0.734 × 10^(-6))
Since both numbers have the same base (10), we can subtract the coefficients and keep the same base and exponent.
= 4.66 × 10^(-5 - (-6))
= 4.66 × 10^(-5 + 6)
= 4.66 × 10^(1)
= 4.66 × 10
= 46.6

which of this options is the answer for the question i just gave you
The answer to your previous question, "Subtract 4.66×10^−5−7.34×10^−7," is -4.5866×10^−5.
To subtract these numbers, we need to make sure the exponents of the numbers are the same.
Step 1: Rewrite the numbers in scientific notation:
4.66 × 10^(-5)
7.34 × 10^(-7)
Step 2: Since the exponents are different, we need to adjust one of the numbers. In this case, we can adjust the second number to match the exponent of the first number.
7.34 × 10^(-7) can be written as 0.734 × 10^(-6) (multiply the number by 10 to increase the exponent by 1).
Step 3: Now that the exponents are the same, we can subtract the numbers:
4.66 × 10^(-5) - 0.734 × 10^(-6) = (4.66 - 0.734) × 10^(-5) = 3.926 × 10^(-5)
So, subtracting the numbers gives us 3.926 × 10^(-5).
To subtract two numbers written in scientific notation, we need to make sure that both numbers have the same exponent.
Given:
4.66 × 10^(-5) - 7.34 × 10^(-7)
Step 1: Adjust exponent
Since both numbers have different exponents, we need to convert them to the same exponent by multiplying or dividing by powers of 10.
Let's convert the second number to match the exponent of the first number, which is -5.
7.34 × 10^(-7) can be written as 0.00000734 × 10^(-5).
Step 2: Subtract the numbers
Now that both numbers have the same exponent, we can subtract them directly.
4.66 × 10^(-5) - 0.00000734 × 10^(-5) = (4.66 - 0.00000734) × 10^(-5)
Calculating the subtraction, we have:
4.65999266 × 10^(-5)
So the result of subtracting 4.66 × 10^(-5) and 7.34 × 10^(-7) is:
4.65999266 × 10^(-5)
