Question

Calculate the difference between the numbers.(9.543 x 10^-5) - (2.544 x 10^-2)

Answer 1

The question requires us to calculate the difference between the numbers 9.543 x 10^-5 and 2.544 x 10^-2.

We can calculate the difference between these numbers by a simple subtraction operation. Note that the first number (9.543 x 10^-5) is more than 100 times smaller than the second number, thus our result must be negative. Also, there are four significant figures in both numbers.

`(9.543*10^(-5))-(2.544*10^(-2))=0.00009543-0.02544=-0.02534=-2.534*10^(-2)`

Therefore the result is -2.534 x 10^-2 (or -0.02534), considering the four significant figures.
