so, It should be multiplied by √2
Pls mark me as the brainliest as I answered first

Answer 2

Answer:

The smallest number which √8 should be multiplied so as to get a rational number  = √2

Step-by-step explanation:

Given number is$\sqrt{8}$

Required to find the smallest number to be multiplied to get a rational number

Solution

We have 8 = 2×2×2

$\sqrt{8} = \sqrt{2X2X2}$

= $\sqrt{2^2X2}$

=2√2

√8=2√2

To get a rational number, we should eliminate the irrational part of it

The irrational we need to eliminate  = √2

The number to be multiplied to eliminate√2  = √2, which is the smallest

∴The smallest number which √8 should be multiplied so as to get a rational number  = √2
