Question

Calculati.
$2 \sqrt{4} + 1 \sqrt{4} =$
$14 \sqrt{8} + 1 \sqrt{13} + 85 =$
${2}^{3} \times {6}^{2} \times {3}^{3} =$
$\frac{8}{10} + \frac{5}{10} + \frac{5}{10} =$
$\sqrt{5} + 9 \sqrt{9} \times \sqrt{2 } =$
$2x + 4xy =$
​

Answer 1

a)=

$2 \times 2 + 2 = 4 + 2 = 6$

b)=

$28 \sqrt{2} + \sqrt{13} + 85$

c)=

$8 \times 36 \times 27 = 7776$

d)=

$\frac{8 + 5 + 5}{10} = \frac{18}{10} = \frac{9}{5}$

e)=

$\sqrt{5} + 9 \times 3 \sqrt{2} = \sqrt{5} + 27 \sqrt{2}$

f)=

$2x \times (1 + 2y)$
