Perform the indicated operations and give the answer in scientific notation.
4.2x10^-4x2.2x10^-3/2x10^2x3.3x10^-2
To perform this operation, we can first simplify the expression in the numerator and then divide by the expression in the denominator.
(4.2 x 10^-4) x (2.2 x 10^-3) = 9.24 x 10^-7
(2 x 10^2) x (3.3 x 10^-2) = 6.6 x 10^0
Now we can divide the two simplified expressions:
(9.24 x 10^-7) / (6.6 x 10^0)
= (9.24 / 6.6) x 10^(-7-0)
= 1.4 x 10^-7
Therefore, the final answer in scientific notation is 1.4 x 10^-7.
