solve 18 into root 50 what type of number is it rational or irrationalsolve root 18 multiplied by root 50 what type of number is it rational or irrational

Answer 1

Hello Mate!

$18 \times \sqrt{50} \\ \sqrt{50} = \sqrt{2 \times 5 \times 5} = 5 \sqrt{2} \\ 18 \times 5 \sqrt{2} = 90 \sqrt{2} \\ here \: 90 \times \sqrt{2} \: is \: irrational$

Because no. multoplyied by irrational is irrational.

Alter :

_/2 = 1.4142.......
90 × 1.4142......=127.278.......

Which is neither repating nor terminating,
Hence its irrational number.

Hope it helps☺!
