Can you please check my answer? im stuck.

What is the solution to (4 * 10^3) x (3x10^4) written in scientific notation
A. 12 x 10^8
B. 1.2 x 10^7
C. 1.2 x 10^8***
D. 12 x 10^7

correct

To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents.

In this case, the coefficients are 4 and 3, and the exponents are 3 and 4.

4 * 3 = 12, and the exponents 3 + 4 = 7.

So, the solution to (4 * 10^3) x (3 * 10^4) in scientific notation is 1.2 x 10^7.

Therefore, the correct answer is B. 1.2 x 10^7.

To find the solution to the expression (4 * 10^3) x (3 * 10^4) written in scientific notation, you need to multiply the coefficients and add the exponents of the powers of 10.

First, multiply the coefficients 4 and 3: 4 * 3 = 12.

Then, add the exponents of the powers of 10: 3 + 4 = 7.

Therefore, the solution in scientific notation is 1.2 x 10^7.

Option B, 1.2 x 10^7, is the correct answer.
