Question

$\sqrt{90}$
​

Answer 1

Answer:

$3\sqrt{10}$

Step-by-step explanation:

$\sqrt{90}$ For now, ignore the square root and focus on number inside

Can the number be divided by a perfect square

• If No, the number simplified
• If Yes, the number isn't simplified

90 can be divided by 9. 9 is $3^{2}$ so we put 3 on the outside of the square root sign. 10 can only be divided by 1, 2, 5, and 10...None of which are perfect squares. 10 stays inside while 3 is on the outside and it is simplified.

3 and 3 which are your PAIRS break down down you get 5 and 2 and you do 5 x 2 which is 10 so you have 3/10
