Question

Which of the following is simplest rationalising factor of √ 75 *
or
√75
or
√25
or
√5
or
√3​

Answer 1

Answer:

$\huge \boxed{ \sqrt{75} \: is \: the \: }$

$\huge \red{rationalising}$

$\huge \green{ factor}$

$\huge \underline{ proof }$

$\sqrt{75} \times \sqrt{75}$

$= ( { \sqrt{75} })^{2}$

$= 75$

$\huge \: hence \:proved$

$\huge \blue{note : - - }$

$we \: can \: cancel \: root \: terms (\sqrt{x} ) \: \\ when \: there \: is \: square$

$\huge \bold \purple{example : - }$

$\huge ( { \sqrt{5} }^{2} ) = \sqrt{5 \times 5}$

$\huge \boxed{==> 5}$
