Answer 1

radic; 108 > 9.4247

Explanation:

Answer 2

This questions can be answered with a calculator, but I have an impression it is meant to be a mental calculation problem, which can be solved as follows.

We know that 10*10=100, in otherwords, &radic; 100 = 10 which is greater than 9.4247.

We also know that &radic; 108 is greater than &radic; 100 =10

So we can conclude that
&radic; 108 > &radic; 100 = 10 > 9.4247
or simply

&radic; 108 > 9.4247

by the transitive property of logical propositions.
