What is the solution to (4 * 10^3) * (3 * 10^4) written in scientific notation?

A. 12 * 10^8
B. 1.2 * 10^7 ****
C. 1.2 * 10^8
D. 12 * 10^7

Could someone please check my answer? That would be great, thank you.

not quite. 4*3 = 12

so, 12*10^7 = 1.2*10^8

4*10^3 * 3*10^4 = 12*10^7 = 1.2*10^8.

Okay, Thank you so much!

To find the solution to the given expression (4 * 10^3) * (3 * 10^4) in scientific notation, we need to multiply the coefficients and add the exponents.

First, let's multiply the coefficients: 4 * 3 = 12.

Next, let's add the exponents: 10^3 * 10^4 = 10^(3+4) = 10^7.

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

So, your answer B. 1.2 * 10^7 is correct! Well done!
