When simplifying expressions with square roots or cube roots, it’s helpful to factor out the numbers under the radical. For example, can be simplified to because . This method can make the arithmetic much simpler and cleaner!

Remember to combine like terms efficiently! In problems like the ones above, separate the coefficients of each radical or root type. For instance, in problem 7, combine the terms and the terms separately to find the answer. This will help avoid any potential errors and keep your calculations organized!
