Answer:
0.00000053
Step-by-step explanation:
The "Eα" (or "eα" depending on the calculator) with α any number, represents the same as 10^α.
In this case we have 5.3E-7 which will be equal to 5.3[10^(-7)]. And 10^(-7) is the same as 1 / (10^7). We need to see what is 10^7:
10^7 = 10*10*10*10*10*10*10 = 10,000,000
And,
1 / 10,000,000 = 0,0000001 (we get as many numbers after the coma than 0s in 10,000,000).
So,
5.3E-7 = 5.3[10^(-7)] = 5.3 * 0,0000001 = 0.00000053
