Question

$\sqrt{49 \times 16}$
$\sqrt{81 \times 49}$
$\sqrt{49 \times 4 = }$
$\sqrt{81 \times 25 = }$
$\sqrt{100 \times 81 = }$

$\sqrt{121 \times 100 = }$
​

Answer 1

Respuesta:

$\sqrt{49 \times 16} \\ = \sqrt{49} \times \sqrt{16} \\ = 7 \times 4 \\ = 28$

$\sqrt{81 \times 49} \\ = \sqrt{81} \times \sqrt{49} \\ = 9 \times 7 \\ = 63$

$\sqrt{49 \times 4} \\ = \sqrt{49} \times \sqrt{4} \\ = 7 \times 2 \\ = 14$

$\sqrt{81 \times 25} \\ = \sqrt{81} \times \sqrt{25} \\ = 9 \times 5 \\ = 45$

$\sqrt{100 \times 81} \\ = \sqrt{100} \times \sqrt{81} \\ = 10 \times 9 \\ = 90$

$\sqrt{121 \times 100} \\ = \sqrt{121} \times \sqrt{100} \\ = 11 \times 10 \\ = 110$
