Answer:
1.1 * 10 ^ -3
Explanation:
Given the value of the thivkness of a dollar bill to be 0.0011metre
The standard scientific notation is expressed as A * 10^n
A is any value between 1 and 10 where n is any integer
0.0011 = 11/10000
0.0011 = 11 *1/1000
0.0011 = 11 * 0.0001
0.0011 = 1.1 * 0.001
0.011 = 1.1 * 10 ^ -3 (Note that the decimal point is shifted forward three times and the power is negative because the value is less than 1)
