Question

root 18 upon 5 root 18 + 3 root 72 - 2root162

Answer 1

Answer:

1+3√72-2√162

Step-by-step explanation:

√18/5√18 + 3√73

√18/5√18 + 3√72-2√162

Now,

Rationalizing the first term,

Therefore,

√18/6√18 x 5√18/5√18

= 5(√18)^2/(5√18)^2

= 5(18)/450

=90/450

=1/5

Now,

Coming to the equation,

Therefore,

1/5+3√72-2√162

= 1+5(3√72)-5(2√162)/5

= 1+15√72-10√162/5

= 5(1+3√72-2√162)/5

= 1 + 3√72 - 2√162
