1/100,000 or 0.00001
5 x 10-10 = 0.0000000005
0.0000115 = 1.15 X 10 -5 ---------------------is this what you mean? Not - 4 but - 5 .
10 to the minus 7 power (10^-7)
It can be: 5+10-5 = 10
5 + (-10) = 5 - 10 = -5
5 x 10-10 = 0.0000000005
5 x 10-4 = 0.0005
10-5 means 1/1051/105 = 1/100,000 = 0.00001
0.0000115 = 1.15 X 10 -5 ---------------------is this what you mean? Not - 4 but - 5 .
-5 minus -15 = 10 5 minus -5 = 10
-10
-10 minus -5 is -5
10 minus 3 and 2/5 = 7 minus 2/5 = 63/5
10 to the power of minus 2
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.
10 to the minus 7 power (10^-7)
4/5 minus 1/2 is the same as 8/10 minus 5/10 = 3/10
