Question
The value of $x^{a-b} \times ^{b-c} x^{c-a}$ is:
✓
Answer
$x^{a-b} \times ^{b-c} x^{c-a}$
$\Rightarrow x^{a-b+c+c-a}$
$\Rightarrow x^0$
$= 1$
$\Rightarrow x^{a-b+c+c-a}$
$\Rightarrow x^0$
$= 1$

A solid metallic cylinder of base radius 3cm and height 5cm is melted to make n solid cones of height 1cm and base radius 1mm. The value of n is.
The curved surface area of one cone is twice that of the other while the slant height of the latter is twice that of the former. The ratio of their radii is:
The distance of the point P(4, 3) from the origin is:
