Question

if x=√7/5 and 5x=p/√7, then the value of p is ?​

Answer 1

Question :-

if x=√7/5 and 5x=p/√7, then the value of p is ?

Answer :-

• p = 7

Step by step explanation :-

Here, we have the value of x and have to find the value of p, now if we put the value of x in the second expression then we will easily find the value of p. Because value of x is already given.

Substituting x in $\rm{5x = \frac{p}{ \sqrt{7} } }$

$\rm:\longmapsto{ \cancel5 \times \frac{ \sqrt{7} }{ \cancel5} = \frac{p}{ \sqrt{7} } } \\ \\ \rm:\longmapsto{ \sqrt{7} = \frac{p}{ \sqrt{7} } } \: \: \: \: \: \: \: \:$

exporting √7 in LHS,

$\rm:\longmapsto{ \sqrt{7} \times \sqrt{7} = p }$

Hence,

$\bf : \longmapsto{p = 7}$
