Answer 1

You simply have to divide $5.5271479$ by $10^{74}$, that is

$$0.\overbrace{000...000}^{\color{red}{73 \,zeros}}55271479 $$

Answer 2

Simply, e$-74=10^{-74}$, so your number is $5.5271479.10^{-74}$

Answer 3

The "E" notation means "multiply by $10$ to this power."

So 2.34E+4 would be $2.34 \times 10^4$, or $23,400$.

Also, -1.23E-2 would be $-1.23 \times 10^{-2}$, or $-0.0123$.

This is a notation that is suited for (now) inexpensive calculators. A simple seven-light character display can handle an $E$ (meaning exponent).
