Rewrite each of the following expressions so that the number inside the radical is as small as possible. For example, rewrite √18 as 3√2. √50= 

√28= 

√252=

1)  

2)

3)

Step-by-step explanation:

We need to simplify the radicals:

1)

First we find prime factors of 50

50 = 2 x 5 x 5

Now,

So,

2)

First we find prime factors of 28

28 = 2 x 2 x 7

Now,

So,

3)

First we find prime factors of 252

50 = 2 x 2 x 3 x 3 x 7

Now,

So,

answer: do you still need this?

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
