Question

if a,b,c are positive then show that:1. bc/a+ca/b+ab/c greater than a+b+c​

Answer 1

Answer:

From the Associative law of Addition

=−8+(−7)+6=−8+(−7)+6

Left hand side (LHS),

=−8+(−7)+6

=−8−7+6

=−15+6

=−9

Right hand side (RHS),

=−8+(−7)+6

=−8+−7+6

=−8+−1

=−8−1

=−9

By comparing LHS and RHS,

LHS=RHS
