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.

The answer is: (2.5x10^4)(4x10^3) = (2.5 x 4) x 10^(4+3) = 10 x 10^7, which is option A.
