JavaScript Simplified - Chapter 42 Exercises

Given the following statement, write a statement that assigns the highest number to the variable big.

let x = 3, y = 2, z = 1;

let big = Math.max(x, y, z);

letbig=Math\.max\(x,y,z\);

Given the following statement, write a statement that assigns the lowest number to the variable small.

let x = 3, y = 2, z = 1;

let small = Math.min(x, y, z);

letsmall=Math\.min\(x,y,z\);

Code a statement that finds the sign of the number represented by y and assigns it to x, which hasn't been declared beforehand.

let x = Math.sign(y);

letx=Math\.sign\(y\);

Code a statement that finds the square root of 64 and assigns it to x, which hasn't been declared beforehand.

let x = Math.sqrt(64);

letx=Math\.sqrt\(64\);

Code a statement that throws away the decimal part of 1.09 and assigns the result to x, which hasn't been declared beforehand.

let x = Math.trunc(1.09);

letx=Math\.trunc\(1\.09\);

Code a statement that raises 4 to the third power and assigns the result to x.

let x = Math.pow(4, 3);

letx=Math\.pow\(4,3\);

Given the following statement, code an alert that displays the largest number multiplied by 3.

let x = 3, y = 2, z = 1;

alert(Math.max(x, y, z) * 3);

alert\(Math\.max\(x,y,z\)\*3\);

Given the following statement, code an alert that displays the largest number multiplied by the smallest number.

let x = 3, y = 2, z = 1;

alert(Math.max(x, y, z) * Math.min(x, y, z));

alert\(Math\.max\(x,y,z\)\*Math\.min\(x,y,z\)\);

Code an alert that displays the square root of 64 multiplied by 2 to the second power.
Click the Result button (or, after revising, don't click, just wait).
Wait a moment.
If you've coded correctly, an alert will display 64.
Dismiss the alert by clicking OK.
