Answer 1

Step-by-step explanation:

Question :-

State with reason whether √20 × √40 is square root or not ?

Solution :-

${\bold{\sf{: \: ⟹ \: \: \: \: \: √20 × √40}}}$

${\bold{\sf{: \: ⟹ \: \: \: \: \: \sqrt{20 \: \times \: 40}}}}$

${\bold{\sf{: ⟹ \: \: \: \: \: \sqrt{(2 \: × \: 2 \: × \: 5)(5 \: × \: 3 \: × \: 3)}}}}$

${\bold{\sf{: ⟹ \: \: \: \: \: \sqrt{(2 \: × \: 2) (5 \: × \: 5) (3 \: × \: 3)}}}}$

${\bold{\sf{: ⟹ \: \: \: \: \: 2 \: × \: 5 \: × \: 3}}}$

${\bold{\sf{: ⟹ \: \: \: \: \: 30}}}$
