Question

Write the Java expressions for the following:

i. (a + b)² + b

ii. z = x³ + y³ + $\dfrac{xy}{3}$​

Answer 1

Java expression for the following:-

1. (a+b)²+b
2. $\sf \: z=x³+y³+ \frac{xy}{3}$

Answer:-

There are two ways to write it as a Java Expression:-

$\sf{(a+b)^2 + b}$

• Math.pow((a+b),2)+b
• ((a+b)*(a+b))+b

$\sf{x^3 + y^3 + (\dfrac{xy}{3})}$

• z=(x*x*x)+(y*y*y)+((x*y)/3);
• z=Math.pow(x,3)+Math.pow(y,3)+((x*y)/3);

Note:-

• Math.pow() returns the number raised to power other number
• It always returns the double type value

More about Math Functions:-

1. Math.max() is used to find the maximum value between 2 numbers. SYNTAX:- Math.max(a,b);
2. Math.min() returns the minimum value between two numbers. SYNTAX:- Math.min(x,y);
3. Math.abs() returns absolute value of the given number. SYNTAX:- Math.abs();
4. Math.ceil() returns rounded value upto nearest higher integer. SYNTAX:- Math.ceil(x);
5. Math.floor() returns rounded value upto nearest lower integer. SYNTAX;- Math.floor(x);
6. Math.round() returns the rounded value of the number upto nearest integer.
7. Math.cbrt() returns cube root of a number. SYNTAX:- Math.cbrt(x);
8. Math.sqrt() returns square root of a number. SYNTAX:- Math.sqrt(x);
