Answer / hi
If it's the Same Question:
Step 1. (0.1)/18-()/20
Step 2. (0.1)((1/18)-(1/20))
Step 3. 0.1 (10-9)/180 -----------> LCM of 18 & 20 = 180
Step 4. 0.1/180
Step 5. 1/1800 is the Answer
Approx = 0.000557
----------------------------------------------------------
If the Question is (0.1)^18-(0.1)^20 then:
Step 1. (10^18/100^18)-(10^20/100^20)
Step 2. (1/10^18)-(1/10^20)
Step 3. 1/10^18(1-1/10^2)
Step 4. 1/10^18(99/100)
Step 5. (99)/(10^20)
