Your question is very good as it contains imaginary number.

A number whose square is negative number is called imaginary number.

Ok now here's the solution:

$\sqrt{ - 25} \times \sqrt{ - 49}$

$= \sqrt{5 \times 5 \times ( - 1)} \times \sqrt{7 \times 7 \times ( - 1)}$

$= 5 \sqrt{ - 1} \times 7 \sqrt{ - 1}$

$= 5 \times 7 \times \sqrt{ - 1} \times \sqrt{ - 1}$

$= 35 \times 1$

$= 35$
