Step-by-step explanation:

Using mid-term break

n²+7n-6n-42=0

n(n+7)-6(n+7)=0

(n-6)(n+7)=0

Either,

n-6=0 OR n+7=0

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, √ 100 = 10 which is greater than 9.4247.

We also know that √ 108  is greater than √ 100 =10

So we can conclude that
√ 108 > √ 100 = 10  > 9.4247
or simply

√ 108 > 9.4247

by the transitive property of logical propositions.
