Question

44) 28 Can you pls solve this one for me and give me the work for it to

Answer 1

Answer:

0.$8\sqrt{7}$ or 2.12

Step-by-step explanation:

To solve this, you have to split 28 into two of its factors. We can choose 7 and 4 (can be multiplied together to get 28):

                                                       28

                                                   7         4

However, 4 can also be split/factored:

                                                       28

                                                   7         4

                                                          2       2

So now we have a a pair of identical terms (being 2), so take this outside of the radical, like so (leave the 7 there):

$(2)(0.4)\sqrt{7}$

0.$8\sqrt{7}$ or 2.12
