Hope u can help me plz

Step-by-step explanation:

Starting with the first one, we know that 3²=9 and 4²=16, so √10 is between 3 and 4. Similarly, √27 is a little over 5. √3 is close to 2, √2 is close to 1, and √9=3, so for simplicity, we can write this as

The 3.something and the 3 kind of cross out, and we're left with 5.something over 2 1.somethings, which can be closer to 2 or 1, which is somewhat unclear -- therefore, our answer can be D or E, and we'll wait on this one

For the second one, we can cross out the √6s to get -- π is a little greater than 3, so this is E, making the first one D

For the third one, we can cross out the √3 to get (3-2)/2 = 1/2, or A as it is between 0 and 1

For the last one, note the multiplication -- cross out the √3 to get (3*2√2)/6, and we get 6√2/6=√2, or C

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
