-4 basically you take 5 from one!
0.0000115 = 1.15 X 10 -5 ---------------------is this what you mean? Not - 4 but - 5 .
10-5 means 1/1051/105 = 1/100,000 = 0.00001
5 to the power of 2
If you mean: 7/1-2/5-5 then the answer is 8/5 or 1.6
If you mean 3/8 minus 1/6 then it is 5/24
That depends what the value of A is.
0.04
3.2x10-4 or 0.00032

3.12 X10^-5 (^-5 = to the power of minus 5)
5 minus 5 sixths is 4 and one sixth.
