Since you are finding a square root, by pairing up like factors, you can easily simplify the expression. It's easy once your calculator tells you it should equal $2$, because you're left with proving $\sqrt{6-4\sqrt{2}}=2-\sqrt{2… On solving the square root we get. Since you are finding a square root, by pairing up like factors, you can easily simplify the expression. however, 3 out of the 4 selections are equivalent to each other, while the 4th one is not. But if the negative is out of the square root. Here's an example: sqrt(-1). Multiplication can be transformed into difference of squares using the rule: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}. Solve your math problems using our free math solver with step-by-step solutions. For our last example, we will simplify a more complicated expression, [latex]\dfrac{10{{b}^{2}}{{c}^{2}}}{c\sqrt[3]{8{{b}^{4}}}}[/latex]. Use the distributive property to multiply 4\sqrt{5} by \sqrt{5}+\sqrt{2}. Using the identities #\sqrt{a}^2=a# and #(a-b)(a+b)=a^2-b^2#, in fact, you can get rid of the roots at the denominator.. Case 1: the denominator consists of a single root. $$ \sqrt[4]{-16} \ and\ \sqrt{-4} $$ If the index n is an odd number, then the radicand do not have to be nonnegative for the root to be a real number. Here ends simplicity. hope you get it First if there is negativer under a square root it will be infinitive or undefined. Consider \left(\sqrt{5}-\sqrt{2}\right)\left(\sqrt{5}+\sqrt{2}\right). An imaginary number can be added to a real number to form another complex number. it will be - 2 square root of 2. because you will keep the negative and solve the square root of eight as positive. Explanation: The imaginary unit is defined as the square root of -1. If we start with a square root set equal to a negative number, we know that squaring both sides will get us into trouble.
