Problem: Divide 1.5 x 10^-5 by 3.5 x 10^-6.
Solution:
(1.5 x 10^-5) / (3.5 x 10^-6)
To divide numbers in scientific notation, divide the coefficients and subtract the exponents:
1.5 / 3.5 = 0.4285714 (approximately 0.43 when rounded to two decimal places)
10^-5 / 10^-6 = 10^-5-(-6) = 10^-5+6 = 10^1 = 10
Therefore, the answer is approximately 0.43 x 10^1 = 4.3 x 10^0 or simply 4.3.

but how would that have a sum of 5 x 10^-5?
My apologies for the oversight. Let's correct that.
Problem: Find two numbers in scientific notation that, when divided, have a sum of 5 x 10^-5.
Let's say the two numbers are A x 10^m and B x 10^n.
Given A x 10^m / B x 10^n = 5 x 10^-5
This can be simplified as A / B = 5 and m - n = -5
Let's choose a suitable pair of numbers that satisfies these conditions.
Let A = 5, B = 1, and m = 0, n = 5
Therefore, 5 x 10^0 / 1 x 10^5 = 5 x 10^-5
So, dividing 5 x 10^0 by 1 x 10^5 gives a sum of 5 x 10^-5.
