Question

va rog ajutor!!! va dau coroana!!!!​

Answer 1

a)

$\sqrt{ {16}^{2} \times {15}^{2} } =$

$16 \times {15}^{2} = 16 \times 225 = 3.600$

$\sqrt{ {18}^{2} \times {7}^{2} \times {2}^{4} } =$

$18 \times {7}^{2} \times 2 {}^{4} = 18 \times 49 \times 16 = 14.112$

$\sqrt{ {3}^{4} \times {5}^{2} \times {2}^{6} } =$

${3}^{4} \times {5}^{2} \times {2}^{4} = 81 \times 25 \times 16 = 32.400$

$\sqrt{ {2}^{8} \times {3}^{4} \times {7}^{2} } =$

${2}^{6} \times {3}^{4} \times {7}^{2} = 64 \times 81 \times 49 = 254.016$

b)

$\sqrt{ \frac{ {15}^{2} }{ {32}^{2} } } = \frac{ {15}^{2} }{32} = \frac{225}{32} = 7.03$

$\sqrt{ \frac{ {2}^{4} \times {3}^{2} }{ {5}^{4} } } = \frac{ {2}^{4} \times {3}^{2} }{ {5}^{2} } = \frac{ {6}^{6} }{ {5}^{2} } = \frac{46.656}{25} = 1.866,24$

$\sqrt{ \frac{ {7}^{2} \times {2}^{2} }{ {3}^{4} } } = \frac{ {14}^{4} }{ {3}^{4} } = \frac{38.416}{81} = 474$

$\sqrt{ \frac{ {25}^{2} }{ {13}^{2} \times {2}^{2} } } = \frac{ {25}^{2} }{13 \times {2}^{2} } = \frac{625}{52} = 12$

$\sqrt{ \frac{ {2}^{2} \times {3}^{4 } \times {5}^{2} }{ {7}^{2} \times {11}^{2} } } = \frac{ {2}^{2} \times {3}^{2} \times {5}^{2} }{ {7}^{2} \times {11}^{2} } = \frac{4 \times 9 \times 25}{9 \times 121} = \frac{900}{1.089} = 0.82$

Trebuie sa plec,dar sper că te-am fost de folos!!!!

CORONIȚĂ???

Te-am făcut restul in poză
