Question

If a=4/5 and b=3/-7,then verify the following relation:-(a+b=b+a)​

Answer 1

Given :-

$\sf{a = \frac{4}{5} } \\ \\ \sf{b = \frac{3}{ - 7} }$

To verify :-

(a + b) = (b + a)

Solution :-

• putting the values of a and b in the relation

$\sf{( a + b) = (b + a)} \\ \\ \sf{ \frac{4}{5} + ( \frac{3}{ - 7} ) = ( \frac{3}{ - 7} ) + \frac{4}{5} } \\ \\ \sf{ \frac{4}{5} - \frac{3}{7 } = - \frac{3}{7} + \frac{4}{5} } \\ \\ \sf{ \frac{28 - 15}{35} = \frac{ - 15 + 28}{35} } \\ \\ \sf{ \frac{13}{35} = \frac{13}{35} }$

LHS = RHS

Hence verified !
