Show that the statement ''For any real numbers `a and b, a^(2) = b^(2)` implies that a = b'' is not true by giving a counter-example.

Text Solution

Verified by Experts

Given statement : for any real numbers a and b , `a^2=b^2` implies that `a=b` , is not true.
Let `a=4` and `b=-4` then `aneb`
`rArra^2=16` and `b^2=16rArra^2=b`
so, `aneb` and `a^2=b^2`
therefore,given statement is not true.
