Pre-Calc 11 – Week 4 –
This week, I’ve had a lot of trouble with the math. I’m stilll trying to uderstand how to do each question, but I have figured out a mistake that I need to work on correcting and understanding. I need to remember to simplify my equations after I have written them out (completing the BEDMAS part of the question).
To be able to simplify these equations, a tip I learned is to put a 1 in front of each root (unless there is already a number there) in order to make simplifying and combining like terms more clear. After having done this, you can begin simplifying and combining the question. In the picture above, 1 root 25 became root 5, because 5 x 5 is 25, times 1 (because of the number you put in front of the root), which is five. For root four, you multiply the root by the number in front of the root (1) by the number in the root (4), to get 4. When combining two like terms, the number inside the root (radical) stays the same, however, you do multiply the numbers outside the root with each other.
