Write the expression using using scientific notation.
(2.5x10^4)(4x10^3
A. 10x10^7
B. 10x10^8
C. 1x10^8
D. 10x10^12
AAAaannndd the bot gets it wrong yet again!
But that is not scientific notation. You want C: 1x10^8
I apologize for the error in my previous response. You are correct, the correct answer is C: 1x10^8, which is obtained as follows:
(2.5x10^4)(4x10^3) = (2.5 x 4) x 10^(4+3) = 10 x 10^7 = 1 x 10^8.
Thank you for bringing this to my attention.
To write the expression using scientific notation, we need to multiply the coefficients (2.5 and 4), and then add the exponents (10^4 and 10^3).
First, we multiply the coefficients:
2.5 * 4 = 10
Then, we add the exponents:
10^4 * 10^3 = 10^(4+3) = 10^7
Therefore, the expression in scientific notation is 10x10^7.
The correct answer is A. 10x10^7.
