Consider a proposition given as:
$x \geq 6$, if $x^2 \geq 25 $ and and its proof as:
If $x \geq 6$, then $x^2 =x.x \geq 6.6 = 36 \geq 25$
Which of the following is correct with respect to the given proposition and its proof?
- The proof shows the converse
- The proof starts by assuming what is to be shown
- The proof is correct and there is nothing wrong
- $i$ only
- $iii$ only
- $i$ and $ii$
- $ii$ only
