Put these in order from least to greatest <br> 2.17x10^-2, 4.18x10^-4, 3.26x10^-3

MaRussiya [10]

Answer:

Step-by-step explanation:

2.17 * 10-2 = 2.17 * 1/(10^2) = 2.17 / 100 = 0.0217

4.18 * 10^-4 = 4.18 * 1 / (10^4) = 4.18 / 10000 = 0.000418

3.26 x 10^-3 = 3.16 * 1 / (10^3) = 3.16 / 1000 = 0.00316

least to greatest is :

(1) 4.18 * 10^-4

(2) 3.26 * 10^-3

(3) 2.17 * 10^-2
