Expand (x−y−z)(x−y−z) (x - y - z) (x - y - z) by multiplying each term in the first expression by each term in the second expression.

Find the shortest distance from the origin to the surface of $xyz^2=2$, i.e. minimize $f (x,y,z)=x^2+y^2+z^2$ subject to $xyz^2-2=0$ hence we obtain $L (x,y,z,\lambda)=x^2+y^2+z^2+\lambda (xyz^2-2)$,t...

Determine (y-x) if 15xy^2 and 21xy are perfect squares, where x and y are positive integers, what is the smallest value of (x+y)?

What is (xyz)^2 ?

2017年9月1日 · (xyz)^2 is an expression which can be rewritten by applying the exponent to each factor within the parentheses. This means that the expression can be expanded as follows: This is because the exponent '2' means to multiply the base by itself.

It is known that the formula for (a + b) 2 = a 2 + b 2 + 2 a b. Rewrite the expression for x - y - z 2 a s x + - y - z 2 and use the mentioned formula to simplify:

2021年7月2日 · Answer: The shortest distance from origin to the given curve is 2 units Step-by-step explanation: The given geometrical surface in the Cartesian co-ordinate system is We can rewrite the curve in the following way Consider any arbitrary point on this surface as P (x,y,z).This point can also be represented as
