402. Вычисляем:
- a) $$\sqrt{11^4} = \sqrt{(11^2)^2} = 11^2 = 121$$
- б) $$\sqrt{4^6} = \sqrt{(4^3)^2} = 4^3 = 64$$
- в) $$\sqrt{(-3)^6} = \sqrt{((-3)^3)^2} = |-3^3| = |-27| = 27$$
- г) $$\sqrt{(-6)^4} = \sqrt{((-6)^2)^2} = |-6^2| = |36| = 36$$
- д) $$\sqrt{2^8 · 3^2} = \sqrt{(2^4)^2 · 3^2} = \sqrt{(2^4 · 3)^2} = 2^4 · 3 = 16 · 3 = 48$$
- е) $$\sqrt{3^4 · 5^6} = \sqrt{(3^2)^2 · (5^3)^2} = \sqrt{(3^2 · 5^3)^2} = 3^2 · 5^3 = 9 · 125 = 1125$$
- ж) $$\sqrt{7^2 · 2^8} = \sqrt{7^2 · (2^4)^2} = \sqrt{(7 · 2^4)^2} = 7 · 2^4 = 7 · 16 = 112$$
- з) $$\sqrt{3^6 · 5^4} = \sqrt{(3^3)^2 · (5^2)^2} = \sqrt{(3^3 · 5^2)^2} = 3^3 · 5^2 = 27 · 25 = 675$$
- и) $$\sqrt{8^4 · 5^6} = \sqrt{(8^2)^2 · (5^3)^2} = \sqrt{(8^2 · 5^3)^2} = 8^2 · 5^3 = 64 · 125 = 8000$$
