Simplifying
Simplify the expression , where one of the square roots must be simplified before the terms can be combined.
The two terms do not initially appear to be like radicals because their radicands ( and ) are different. Simplify by extracting its largest perfect square factor:
Now rewrite the original expression with the simplified radical:
Both terms contain , so they are like radicals. Combine the coefficients: .
This example illustrates that a radical expression which appears to contain unlike terms may actually contain like radicals once each square root has been simplified.

While reviewing the mathematical formulas used to calculate material dimensions for a new manufacturing project, you encounter several expressions with square roots. To simplify these expressions correctly, which rule must you recall regarding the addition and subtraction of square roots?
A quality control analyst is simplifying the expression 8√5 + 2√5 for a report. Following the rule for adding like square roots, the resulting coefficient in front of the √5 is ____.
When a technician is documenting the total length of two wiring segments, 5√2 meters and 3√2 meters, the rule for adding 'like square roots' states that the coefficients should be added while the radicand (2) remains unchanged.
An inventory manager is totaling the weights of two batches of metal alloy, recorded as 9√5 kg and √5 kg. To simplify the total weight (9√5 + √5), arrange the following steps in the correct order based on the rule for adding like square roots.
A maintenance team is organizing an inventory of metal tubing. The lengths of various segments are recorded using square root expressions. Match each pair of tubing measurements with its correctly simplified total length or difference, based on the rules for adding and subtracting like square roots.

A maintenance technician is measuring two lengths of copper tubing for a repair. The first length is inches and the second length is inches. To simplify the first measurement so it can be added to the second, which perfect square factor of 20 must the technician recall?
A specialized technician is combining two lengths of material, centimeters and centimeters, for a structural repair. To add these together as 'like radicals,' the technician must simplify so that it has the same radicand as the second term. Which value represents this common radicand?
