**How to solve [math]\sqrt{x-7}=x-7[/math] Quora**

Square the 8 and then cube root that product Either way, the equation simplifies to 4. Depending on the original expression, though, you may find the problem easier if you take the root first and then take the power, or you may want to take the power first.... One example of an irrational number is when you have a root of an expression that is not a perfect root, for example, the square root of 7 or the cube root of 2. So when we rationalize either the denominator or numerator we want to rid it of radicals.

Watch video · This is equal to 2 times the square root of 13. 2 times the principal square root of 13, I should say, times i. And I just switched around the order. It makes it a little bit easier to read if I put the i after the numbers over here. But I'm just multiplying i times 2 times the square root of 13. That's the same thing as multiplying 2 times the principal square root of 13 times i. And I think...A square root is an exponent of one-half. A cube root is an exponent of one-third. Square roots of negative numbers do not have real number roots since the product of …

## How To Get Rid Of A Square Root Of X

### There are two common ways to simplify radical expressions, depending on the denominator. Using the identities #\sqrt{a}^2=a# and #(a-b)(a+b)=a^2-b^2#, in fact, you can get rid of …

- When solving square root problems, sometimes you get answers that are not correct, so make sure you plug your answer into the original question to see if it is correct. In this case the only correct answers are x = 4 or x = 20 because they both check.
- You get rid of the square root first. [math]\sqrt{(x-7)} = (x-7)[/math] so you are looking for answers where sqrt(x-7) >= 0 (where the square root of x - 7 is greater than or equal to zero. So, the smallest x value possible is 7, which of course is one of the solutions as 0 = 0. Now that you know the boundaries and have a single solution, divide both sides by the square root, which gives
- Because this term is squared, you need to get rid of the parentheses by squaring it and listing out the individual terms. 2) To eliminate square roots, you have to multiply, so you need to look for opportunities to multiply a root by another to "square out the root".
- The term 'the square root of X' is not quite precise as there are usually 2 square roots called sqrt(X) and -sqrt(X) sqrt(x^2) = abs(x) This is the positive square root of x^2. -sqrt(x^2) = -abs(x) is also a square root of x^2 It's tempting to say sqrt(x^2) = x, but that's only true for x>=0 .
