a)
[tex] \sqrt{ {7}^{4} \times {4}^{2} } = \sqrt{ {7}^{2} \times {7}^{2} \times {2}^{2} \times {2}^{2} } = 7 \times 7 \times 2 \times 2 = 49 \times 4 = 196[/tex]
b)
[tex] \sqrt[3]{ {3}^{6} \times {10}^{3} } = \sqrt[3]{ {3}^{3} \times {3}^{3} \times {10}^{3} } = 3 \times 3 \times 10 = 9 \times 10 = 90[/tex]
c)
[tex] \sqrt{ {5}^{4} \times {2}^{6} \times {7}^{2} } = \sqrt{ {5}^{2} \times {5}^{2} \times {2}^{2} \times {2}^{2} \times {2}^{2} \times {7}^{2} } = 5 \times 5 \times 2 \times 2 \times 2 \times 7 = 25 \times 8 \times 7 = 200 \times 7 = 1400[/tex]
d)
[tex] \sqrt[3]{ {3}^{3} \times {10}^{6} \times {2}^{9} } = \sqrt[3]{ {3}^{3} \times {10}^{3} \times {10}^{3} \times {2}^{3} \times {2}^{3} \times {2}^{3} } = 3 \times 10 \times 10 \times 2 \times 2 \times 2 = 300 \times 8 = 2400[/tex]
