Question

write the java expression for​

Answer 1

$\textsf{\large \textbf{Given Expression}}$

   $a = \sqrt[3]{x^2 + 3y - z}$

$\textsf{\large \textbf{Java Expression}}$

   $\texttt{a = Math.cbrt(x * x + 3 * y - z)}$

Answer 2

$\underline{\large{\sf{Question:}}}$

• $\large{\tt{a \: = \: \sqrt[3]{x {}^{2} \: + \: 3y \: - \: z } }}$

$\underline{\large{\sf{Required \: Answer:}}}$

• Here we would be only using Math.cbrt method because of the cube root.

$\red \bigstar \: \boxed{\large{ \sf{a \: = \:Math.cbrt(x \: * \: x + 3 \: * \: y \: - \: 2}}} \red \bigstar$

• Method is a named block of a códe in a class. It is executed within a defined set of instructions.
• Methods and variables of math class are defined as static members.
• Java.lang package contains classes and interfaces which are fundamental to Java programming language.
• The math class of java.lang package contains generic mathematical functions including some geometric and trigonometric function.

• Math.ceil returns smallest integer which is greater or equal to the argument.
• Math.abs returns us the absolute value of a given argument.
• Math.pow it returns us the value of a first given argument raised to the power of the given second argument.
• Double datatype is used if a output comes in decimal.
