Question

which is the biggest number 5 root 5, 7 root 2, 3 root 5, 2 root 13​

Answer 1

Answer:

hey mate! Here's ur Answer

Step-by-step explanation:

Let us send the number (which is not under the root) into the root.Then u will get the value of that irrational number . Finally, u will be able to determine the bigger number.

A number which is not under root can be written as (✓a) square ....so that when you cancel the square and root u get back the same number again!!!

5✓5 = ✓5*5*5 = ✓125

7✓2 = ✓7*7*2 = ✓98

3✓5 = ✓3*3*5 = ✓45

2✓13 = ✓2*2*13 = ✓52

so u can pick the bigger number among these and get the answer

Answer 2

The biggest number is 5 root 5

Solution:

Given that,

We have to find the greatest number

5 root 5, 7 root 2, 3 root 5, 2 root 13​

Write them in decimals

$5 \sqrt{5} = 11.180 \\\\7 \sqrt{2} = 9.899 \\\\3 \sqrt{5} = 6.708 \\\\2 \sqrt{13} = 7.211$

Arrange them from greatest to smallest

11.180 , 9.899 , 7.211 , 6.708

Greatest number : 11.180

Which is $5 \sqrt{5}$

Thus the biggest number is 5 root 5
