Answer:
Step-by-step explanation:
1.
1.365 x 10^1 = 13.65
1.365 x 10^2 = 136.5
1.365 x 10^3 = 1365
2.
571.4 / 10^1 = 57.14
571.4 / 10^2 = 5.714
571.4 / 10^3 = 0.5714
3.
479 x 10^(-1) = 4.79 * 10^1 = 47.9
479 x 10^(-2) = 4.79 * 10^0 = 4.79
479 x 10^(-3) = 4.79 * 10^(-1) = 0.479
4.
89.15 x 10^3 = 8.95 * 10^4 = 89500
5.
217.5 / 10^2 = 2.175
6.
I can't see if that is a comma or period, so I will do both
4,000 x 10^(-3) = 4 * 10^(0) = 4
4.000 x 10^(-3) = 4 * 10^(-3) = 0.004
7.
89.25 / 10^1 = 8.925
8.
3.107 x 10^1 = 31.07
9.
45.2 / 10^3 = 0.0452
10.
2,100 x 10^(-2) = 2.1 * 10^1 = 21
11.
5.7 / 10^3 = 0.0057
12.
I can't see if that is a 2 or 3, so I will do both. Standard form refers to the usual way that numbers are written. Power to the 3 means move the decimal right 3 places, while power to the 2 means move the decimal right 2 places.
4.26 x 10^(3) = 4260
4.26 x 10^(2) = 426
