Bot was wrong 1 & last were 1.632 x 10^7 & 2.08 x 10^7
Apologies for the previous incorrect response. You are correct.
The correct answer is 1.632 x 10^7 for the first question and 2.08 x 10^7 for the last question. Thank you for catching that mistake.
To find the product of two numbers in scientific notation, you need to multiply the coefficients and add the exponents.
In this case, you have (5.1 x 10^3) x (3.2 x 10^3).
First, multiply the coefficients: 5.1 x 3.2 = 16.32.
Next, add the exponents: 10^3 x 10^3 = 10^(3+3) = 10^6.
Therefore, the product is 16.32 x 10^6.
The correct response is: 16.32 x 10^6
