Question

Which among the following product are natural numbers? a)√10 × √2 b)√12 × √3 c)√10 × 1 √2 d)√12 × 1 √3 e)√5 × √8​

Answer 1

Answer:

(b)

Step-by-step explanation:

(b) √12×√3=√36

√36=6

Answer 2

• First we will check the products of all numbers then we will write conclusion..

$a) \: \sqrt{10} \times \sqrt{2} \\ = \sqrt{20} \\ = 2 \sqrt{5}$

$b) \sqrt{12} \times \sqrt{3} \\ = \sqrt{36} \\ = 6$

$c) \: \sqrt{10} \times 1 \sqrt{2} \\ = \sqrt{10} \times \sqrt{2} \\ = \sqrt{20} \\ = 2 \sqrt{5}$

$d) \: \sqrt{12} \times 1 \sqrt{3} \\ = \sqrt{12} \times \sqrt{3} \\ = \sqrt{36} \\ = 6$

$e) \sqrt{5} \times \sqrt{8} \\ = \sqrt{40} \\ = 2 \sqrt{10}$

Hence, Option B & D are correct..

Note;

• You can tick any of the option from B and D if can tick only one but if you can tick two options tick option B and D.
