What is 5.5×104 multiplied by 2.2×10−8? Write the answer in scientific notation. (1 point)
A. 1.21 × 10^−4
B. 12.1 x 10^-4
C. 1.21 x 10^-5
D. 1.21 x 10^-3
I apologize for the previous incorrect answers. Let's solve it correctly this time.
To multiply numbers in scientific notation, you multiply the coefficients and add the exponents.
(5.5 × 10^4) multiplied by (2.2 × 10^-8) can be calculated as follows:
5.5 × 2.2 = 12.1 (the coefficient)
10^4 × 10^-8 = 10^(4 - 8) = 10^-4 (the exponent)
So, the final answer in scientific notation is 1.21 × 10^-3.
The correct answer is (D) 1.21 × 10^-3.
To multiply two numbers in scientific notation, you need to multiply their decimal parts and add their exponents.
In this case, we have:
5.5 × 10^4 × 2.2 × 10^-8
To multiply 5.5 and 2.2, simply multiply the decimal parts:
5.5 × 2.2 = 12.1
Next, add the exponents:
10^4 × 10^-8 = 10^(4-8) = 10^-4
So the final result in scientific notation is 12.1 × 10^-4.
Comparing this to the answer choices:
A. 1.21 × 10^-4
B. 12.1 x 10^-4
C. 1.21 x 10^-5
D. 1.21 x 10^-3
We can see that the correct answer is option B. 12.1 × 10^-4.
thats wrong
still wrong
wrong
correct!
Thank you for confirming. I apologize for the previous mistakes but I'm glad to provide the correct answer this time. If you have any more questions, feel free to ask.
To multiply numbers written in scientific notation, you multiply the coefficients and add the exponents.
(5.5 x 10^4) x (2.2 x 10^-8) can be rewritten as (5.5 x 2.2) x (10^4 x 10^-8)
Multiplying the coefficients, we get 12.1, and multiplying the powers of 10, we get 10^-4.
Therefore, the answer is 12.1 x 10^-4.
The correct answer is (B) 12.1 x 10^-4.
Apologies for the mistake. Let's try solving it correctly.
