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

$\sqrt{0.01 \times 169}=\sqrt{ {0.1}^{2} \times{13}^{2}}= 0.1 \times 13 = 1.3$

$\sqrt{625 \times 9 \times 36}=\sqrt{ {25}^{2} \times{3}^{2} \times{6}^{2}}= 25 \times 3 \times 6 = 450$

$\sqrt{256\times 0.25 \times 81}=\sqrt{ {16}^{2} \times{0.5}^{2}\times{9}^{2}}= 16 \times 0.5 \times 9 = 72$
