Find √49x 25 and show that it is equal to √49x√√25.​

Answer 1

$\sqrt{49} \times 25 = \sqrt{49} \times \sqrt{ \sqrt{25} } \\ \\ \sqrt{7 \times 7} \times ( {5)}^{2} = \sqrt{7 \times 7} \times \sqrt{5 \times 5} \\ \\ 7 \times 5 = 7 \times 5 \\ \\ 35 = 35$

Answer 2

Number 4998 satisfies all the given conditions. Last digit (8) is twice the first digit (4). Second digit (9) and the third digit (9) are the same.
