Answer 2

Answer:

$\sqrt{15} \times \sqrt{-15}$ = 15 $\iota$

Step-by-step explanation:

We have been given to find the value of $\sqrt{15} \times \sqrt{-15}$

We can re-write it as,

= $\sqrt{15} \times \sqrt{15} \times \sqrt{-1}$

Multiplication of root 15 and root 15 would result to be 15:-

= 15 x $\sqrt{-1}$

= 15$\sqrt{-1}$

As the root of a negative integer is not possible..

We would be using the concept of Iota to solve this question further:-

= 15 $\iota$

So, the answer to this question is 15 $\iota$ !
