Answer 1

a)
$\sqrt{2.5^2} - \sqrt{3^5} - \sqrt{2.3^4} + \sqrt{2^2.3.5^2=}$

$5 \sqrt{2} -9 \sqrt{3} -9 \sqrt{2} +10 \sqrt{3} =$

$\fbox{ \sqrt{3} -4 \sqrt{2} }$

b)
$\sqrt{3} -7 \sqrt{2.3^2} +5 \sqrt{2^4.3} + \sqrt{2^3.5^2} =$

$\sqrt{3} -7.3 \sqrt{2} +5.2^2 \sqrt{3} +2.5 \sqrt{2} =$

$\sqrt{3} -21 \sqrt{2} +20 \sqrt{3} +10 \sqrt{2} =$

$\fbox{ 21 \sqrt{3} -11 \sqrt{2} }$

c)
$\fbox{ 21 \sqrt{2} -10 \sqrt{3} }$

d)
$6 \sqrt{2^3} + \sqrt{2^5} -2 \sqrt{2.5^2} =$

$6.2 \sqrt{2} +2^2 \sqrt{2} -2.5 \sqrt{2} =$

$12 \sqrt{2} +4 \sqrt{2} -10 \sqrt{2} =$

$\fbox{ 6 \sqrt{2} }$
