Answer:
1. = 2.077 × 10-4
(scientific notation)
2. = 2.077e-4
(scientific e notation)
3. = 207.7 × 10-6
(engineering notation)
(millionth; prefix micro- (u))
4. = 0.0002077
(real number)
2.077[tex]^{-4}[/tex] is the answer. You would want to put your decimal point after the first number that is not 0. So by moving 4 spaces to the right (which would make the exponent a negative), your decimal point would be right after the 2.
