what is 5.5*10^4 multiplied by 2.2*10^-8 write the answer in scientific notation
1.21*10^-3
1.21*10^-5
1.21*10^-4
12.1*10^-4
The answer is 1.21*10^-3.
a tape dispenser holds 1.14*10^4 mm of the tape that is 12.7 mm wide multiply the two numbers to find the total area in square millimeter's of tape write the product in scientific notation
14.478*10^5mm^2
1.4478*10^4mm^2
1.4478*10^5mm^2
14.478*10^4mm^2
The product is 1.4478*10^5 mm^2.
To find the product of the two numbers in scientific notation, you can multiply the coefficients and add the exponents.
(5.5 * 10^4) * (2.2 * 10^-8)
= (5.5 * 2.2) * (10^4 * 10^-8)
= 12.1 * 10^-4
Therefore, the answer is 12.1 * 10^-4.
To multiply the two numbers written in scientific notation, you need to multiply the decimal parts first and then multiply the powers of 10.
Let's multiply the decimal parts:
5.5 * 2.2 = 12.1
Now let's multiply the powers of 10:
10^4 * 10^-8 = 10^(4-8) = 10^-4
Putting it all together, the answer is 12.1 × 10^-4. So, the correct option is: 1.21 × 10^-3.
