√3 * √3.63 = √3 * √(3*1.21) = √3*√3 *√1.1² = 3*1.1 = 3.3

√(48*98*150) = √((16*3)(2*49)(2*3*25) = √(2⁴*3²*2²*5²*7²) = 4*3*2*5*7 = 840

√(25*81/4) = √(5²*9²/2²) = 5*9/2 = 45/2 = 22.5

Answer 2

1)3,3

2)840

3)22,5

Объяснение:

1.

$\sqrt{3 } \times \sqrt{3.63} = \sqrt{3 \times 3×1,1×1,1} = \\ = 3×1,1 = 3.3$

2.

$\sqrt{48 \times 98 \times 150} = \\ = \sqrt{6 \times 8 \times 49 \times 2 \times 25 \times 6} = \\ = \sqrt{6 \times 6 \times 8 \times 2 \times 49 \times 25} = \\ = \sqrt{36 \times 16 \times 49 \times 25} = \\ = \sqrt{36} \times \sqrt{16} \times \sqrt{49} \times \sqrt{25} = \\ = 6 \times 4 \times 7 \times 5 = 42 \times 20 = \\ = 840$

3.

$\sqrt{ \frac{25 \times 81}{4} } = \frac{ \sqrt{25} \times \sqrt{81} }{ \sqrt{4} } = \\ = \frac{5 \times 9}{2} = \frac{45}{2} = 22.5$

1) 3,3

2) 840

3) 22.5
