Question

√7*(2√7) = ?
√13,69*4= ?
√28*63= ?
√75/√3= ?
2 в 4 степени * 5 в 2 степени=?

Answer 1

1)
$sqrt{7} times (2 times sqrt{7} ) = 7 times 2 = 14$

2)

$sqrt{13.69 times 4} = 7.4$


3)
$sqrt{28 times 63} = sqrt{1764} = 42$
4)
$sqrt{ frac{75}{3} } = sqrt{25} = 5$
5)
${2}^{4} times {5}^{2} = 16 times 25 = 400$
