а) 7$$\sqrt{10}$$ = $$\sqrt{7² ⋅ 10}$$ = $$\sqrt{49 ⋅ 10}$$ = $$\sqrt{490}$$
б) 5$$\sqrt{3}$$ = $$\sqrt{5² ⋅ 3}$$ = $$\sqrt{25 ⋅ 3}$$ = $$\sqrt{75}$$
в) 6$$\sqrt{x}$$ = $$\sqrt{6² ⋅ x}$$ = $$\sqrt{36 ⋅ x}$$ = $$\sqrt{36x}$$
г) 10$$\sqrt{y}$$ = $$\sqrt{10² ⋅ y}$$ = $$\sqrt{100 ⋅ y}$$ = $$\sqrt{100y}$$
д) 3$$\sqrt{2a}$$ = $$\sqrt{3² ⋅ 2a}$$ = $$\sqrt{9 ⋅ 2a}$$ = $$\sqrt{18a}$$
е) 5$$\sqrt{3b}$$ = $$\sqrt{5² ⋅ 3b}$$ = $$\sqrt{25 ⋅ 3b}$$ = $$\sqrt{75b}$$
ж) a$$\sqrt{x²}$$ = $$\sqrt{a² ⋅ x²}$$ = $$\sqrt{a²x²}$$
з) m²$$\sqrt{m³}$$ = $$\sqrt{m² ⋅ m³}$$ = $$\sqrt{m⁵}$$
и) 3xy²$$\sqrt{y}$$ = $$\sqrt{3²x²y⁴ ⋅ y}$$ = $$\sqrt{9x²y⁵}$$
