WebA fraction can be an exponent. When a fraction is an exponent, you can change it so that a there is a first, second, third, etc. root of something. For example, 1^1/2 = square root of 1 1^1/3 = third root of 1 1^1/4 = fourth root of 1 And so on and so forth. This was covered in a series of videos in the topic Rational Exponents and Radicals. WebI thought I knew root notation quite well, but now I am confused, and various sources say different things. So how much is $\sqrt[3]{-27}$? Wikipedia and google both clearly state that the solution would be $-3$ with this notation. However, it has complex principal root $1.5 + 2.59... * i$, which is the Wolfram alpha's solution.

WebYes, you are correct. Square root of 9 is indeed +3 or -3, which can be written as ±3. In fact any even roots (square root, fourth root, sixth roots, and so on) has two solutions, a positive and a negative. However, when we say "the square root" we often refer to the principal square root, which denotes as √ (n). WebThis is the exact same thing. This is the exact same thing as 8 to the 1/3 power times x to the sixth to the 1/3 power. And then all of that is being multiplied by 15. And so 8 to the 1/3 power-- that's the same thing as the cube root of 8. You might recognize that 8 is 2 times 2 times 2. So 8 to the 1/3 power is 2. 8 is 2 to the third. WebThe 3rd root is denoted by the sign – 3 √. 3√y = x (root 3 of y, equals x) x3 = y (in turn, when raising x to the 3rd power, we get the required number y) n-th root (n√) calculator online … one day bus tours nyc
