Possible Answers:. Correct answer:. Explanation : When multiplying square roots, you are allowed to multiply the numbers inside the square root. Report an Error. Explanation : To simplify the problem, just distribute the radical to each term in the parentheses.
Evaluate and simplify:. Explanation : To multiply square roots, we multiply the numbers inside the radical and we can simplify them if possible. Simplify and evaluate:. In this case, let's simplify each individual radical and multiply them. Explanation : To multiply square roots, we multiply the numbers inside the radical.
Any numbers outside the radical are also multiplied. We can simplify them if possible. Copyright Notice. Virdah Certified Tutor. Beverly Certified Tutor. Wesleyan University, Bachelors, Mathematics. Anthony Certified Tutor. We will first distribute and then simplify the square roots when possible.
When we worked with polynomials, we multiplied binomials by binomials. Remember, this gave us four products before we combined any like terms.
To be sure to get all four products, we organized our work—usually by the FOIL method. Note that some special products made our work easier when we multiplied binomials earlier. This is true when we multiply square roots, too. The special product formulas we used are shown below. We will use the special product formulas in the next few examples.
We will start with the Binomial Squares formula. Be sure to include the term when squaring a binomial. Access these online resources for additional instruction and practice with multiplying square roots.
A landscaper wants to put a square reflecting pool next to a triangular deck, as shown below. The triangular deck is a right triangle, with legs of length 9 feet and 11 feet, and the pool will be adjacent to the hypotenuse.
An artist wants to make a small monument in the shape of a square base topped by a right triangle, as shown below. The square base will be adjacent to one leg of the triangle. The other leg of the triangle will measure 2 feet and the hypotenuse will be 5 feet. A square garden will be made with a stone border on one edge.
If only feet of stone are available, simplify to determine the area of the largest such garden.
