(2.0*10^4)(3.0*10^3)
A. 6.0 * 10^7
B. 6.0 * 10^12 my answer
C. 6.0 * 10^5
D. 6.0 * 10^43
no ... the exponents add
You are not correct...yet!
THe 6 is correct, but remember that you have
10^4 x 10^3
that is
10x10x10x10 x 10 x 10 x 10
thus 10^7
So which answer would you now choose?
Oh! so, it's A?
Yes : )
To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents.
In this case, we have (2.0 * 10^4)(3.0 * 10^3).
First, let's multiply the coefficients: 2.0 * 3.0 = 6.0.
Next, let's add the exponents: 10^4 * 10^3 = 10^(4+3) = 10^7.
So, the result becomes 6.0 * 10^7.
Therefore, the correct answer is option A. 6.0 * 10^7.
