Question

(2.13 x 10°)(5.6 x 10-7)
How do i work it out

Answer 1

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

Step-by-step explanation:

To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents. In this case, we have (2.13 x 10^0)(5.6 x 10^-7). Multiplying the coefficients gives us 2.13 * 5.6 = 11.928. Adding the exponents gives us 10^0 + 10^-7 = 10^-7.

So the final answer is 11.928 x 10^-7, or simply 1.1928 x 10^-6.
