Chapter 0: Problem 39

Add or subtract terms whenever possible. $$\sqrt{50 x}-\sqrt{8 x}$$

Short Answer

Expert verified
The simplified form of the expression \(\sqrt{50 x}-\sqrt{8 x}\) is \(3\sqrt{2x}\).

Step by step solution

01

Factorize Under the Square Root

First, break down the numbers 50 and 8 into their prime factors: \(50 = 2 * 5^2\) and \(8 = 2^3\). Also note that every number under the square root is multiplied by 'x'. Rewriting the expression gives \(\sqrt{2*5^2*x}-\sqrt{2^3*x}\).
02

Simplify the Square Root

Square root of a product can be expressed as the product of square roots, and square root of a square number will give the number itself. Applying these rules, the expression simplifies to: \(5\sqrt{2x}-2\sqrt{2x}\).
03

Subtraction of Like Terms

Now subtract the like terms \(5\sqrt{2x}-2\sqrt{2x}\) which simplifies to \(3\sqrt{2x}\).

What is a perfect square trinomial and how is it factored?

Fill in each box to make the statement true. $$\sqrt{x}=5 x^{7}$$

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. $$ x^{3}-64-(x+4)\left(x^{2}+4 x-16\right) $$

Evaluate each expression without using a calculator. $$125^{\frac{2}{3}}$$

Simplify each expression. Assume that all variables represent positive numbers. $$ \left(\frac{x^{-\frac{5}{4} y^{\frac{1}{3}}}}{x^{-\frac{3}{4}}}\right)^{-6} $$
