Question

What is the list of numbers written in scientific notation from small to large number one 5.7 * 10 ^ 13 29.3 * 10 ^ - 15 3 4.5 * 10 ^ 4 4 1.9 * 10 ^ 7 5 7.6 * 10 ^ -9

Answer 1

First let's drop the spaces so we see what we have. Then we make them all read in scientific notation; i.e., with the decimal after the first digit and with the E symbol. I will assume that a mathematician would allow the *10^4 to stand for E4 but I don't know that.
5.7*10^13
29.3*10^-15 = 2.93*10^-14
34.5*10^44 = 3,45*10^45
1.9*10^7
57.6*10^-9 = 5.76*10^-8
Now let's arrange the numbers from smallest to largest.
=======================
29.3*10^-15 = 2.93*10^-14 = 2.93E-14
57.6*10^-9 = 5.76*10^-8
1.9*10^7
5.7*10^13
34.5*10^44 = 3.45*10^45
Check these to make sure I've counted the decimals/digiest correctly.
