WebSurds are expressions that contain a square root, cube root or other roots. They are roots of numbers that produce an irrational number as a result, with infinite decimals. Therefore, they are left in their root form to represent them more exactly. For example, $\sqrt2, \sqrt 3, \sqrt5, \sqrt 6, \sqrt 7, 2\sqrt 2$. Web2. Compute without using a calculator. Explain how you know that your answer is 10 −2 correct. 10^-2 is equal to 0.01. This is because 10^2 is 100. Being that the exponent is now negative, you have to divide it instead of multiply it. So, you would work down the pattern and take 10^0 which is 1 then divide it by 100 to get the negative exponent.
