216 = 2³·3³

1000 = 2³·5³

62 = 2·31

58 = 2·29

490 = 2·5·7²

30 = 2·3·5

156 = 2² ·3 ·13

430 = 2·5 ·43

128 = 2⁷

1024 = 2¹⁰

324 = 2²·3⁴

243 = 3⁵

729 = 3⁶

Answer 2

$\bf 225 = 3^{2}\cdot 5^{2}$

$\bf 6400 = 2^{8}\cdot 5^{2}$

$\bf 245 = 5\cdot 7^{2}$

$\bf 216 = 2^{3}\cdot 3^{3}$

$\bf 1000 = 2^{3}\cdot 5^{3}$

$\bf 62 = 2\cdot 31$

$\bf 58 = 2\cdot 29$

$\bf 490 = 2\cdot 5\cdot 7^{2}$

$\bf 30 = 2\cdot 3\cdot 5$

$\bf 156 = 2^{2}\cdot 3\cdot 13$

$\bf 430 = 2\cdot 5\cdot 43$

$\bf 128 = 2^{7}$

$\bf 1024 = 2^{10}$

$\bf 324 = 2^{2}\cdot3^{4}$

$\bf 324 = 3^{5}$

$\bf 729 = 3^{6}$
