###### Hi I need help with this maths question pls

I would go about this by trying to put everything within the square root using your surds laws.

For example (not using your numbers to allow you to have a go!):

5 * root3 = root25 * root3 = root75

6 * root5 = root36 * root5 = root180

Therefore, 5root3 < 6root5 as root180 > root75.

This makes sense as 6 is larger than 5; and root 5 is larger than root 3, so it stands to reason that 6 * root5 > 5 * root3.

For example (not using your numbers to allow you to have a go!):

5 * root3 = root25 * root3 = root75

6 * root5 = root36 * root5 = root180

Therefore, 5root3 < 6root5 as root180 > root75.

This makes sense as 6 is larger than 5; and root 5 is larger than root 3, so it stands to reason that 6 * root5 > 5 * root3.

To me I understand the comment above me but it feels like they got the root backwards as they have the five times the root not in it (though maybe I'm the one misreading it)

So you want 7, 4β2, 2β7, 3β5 in order?

I would try to put them all as unsimplified surds though,

7 = β49,

4β2 = β16 * β2,

2β7 = β4 * β7,

3β5 = β9 * β5,

So you want 7, 4β2, 2β7, 3β5 in order?
