What are grouping symbols?
Grouping symbols are symbols such as parentheses or brackets, that indicate that the operations within them should be done first. When an expression contains more than one pair of grouping symbols, the computations in the innermost grouping should be done first.
Why is it important to always factor the radicand first when simplifying radicals?
The question is based on the premise that It is not possible to simplify a radical without first factorising it. That is simply not true. Beginners may find it a useful step but that does not make it "important to always factor".Simplifying radicals entails removing square factors of the radicand from under the radical. This can be done without factoring first.
How to solve a pemdas rule?
p --- stands for parenthesis, but you do all grouping symbols 1st. e -- stands for exponents, but include radicals (sq roots) are 2nd md -- stands for multiplication and division done from right to left ( not necessarily multiply first) done 3rd as -- stands for addition and subtraction just like md from left to right this is done last
