ii) 6√7 × 2√7
iii) 6√15÷3√5

Answer 1

Question :

Solve the following :

i) (2√5+3√3) + (3√5+ 4√3)

ii) 6√7 × 2√7

iii) 6√15÷3√5

Solution :

$\sf \small i) (2√5+3√3) + (3√5+ 4√3)$

$\sf \small \rightarrow2√5+3√5+ 3√3+ 4√3$

$\sf \small \rightarrow 5√5+7√3$

$\boxed{\sf \small Hence \: the \: answer \: is \green{\underline{\: 5√5 + 7√3}}}$

$\sf \small ii) 6√7 × 2√7$

$\sf \small \rightarrow6 \times 2 \times \sqrt{7} \times \sqrt{7}$

$\sf \small \rightarrow8 \times {( \sqrt{7} )}^{2}$

$\sf \small \rightarrow8 \times 7$

$\sf \small \rightarrow56$

$\boxed{\sf \small Hence \: the \: answer \: i s \: \: { \orange{ \underline{ \pink{56}}}}}$

$\sf \small iii) 6√15÷3√5$

$\sf \small \rightarrow \frac{6 \sqrt{15} }{3 \sqrt{5} }$

$\sf \small \rightarrow2 \sqrt{5}$

$\boxed{\sf \small Hence \: the \: answer \: i s \: \: { \orange{ \underline{ \blue{2 \sqrt{5} }}}}}$
