If $x+y=-4,$ then what is the value of $x^{3}+y^{3}-12 x y+64 ?$

By remainder Theorem find the remainder, when $p(x)$ is divided by $g(x),$ where

$p(x)=x^{3}-6 x^{2}+2 x-4, \quad g(x)=1-\frac{3}{2} x$

Evaluate the following using suitable identities

$(995)^{3}$

Expand the following:

$(-x+2 y-3 z)^{2}$

Multiply $x^{2}+4 y^{2}+z^{2}+2 x y+x z-2 y z$ by $(-z+x-2 y)$

The degree of polynomial $7 x^{5}-4 x^{4}+2\left(x^{3}\right)^{2}-x^{2}+35$ is $\ldots \ldots \ldots$
