Final answer:
To change a decimal into surds, you need to express the decimal as a square root. Follow these steps: convert the decimal into a fraction, simplify the fraction, find a square root equal to the simplified fraction, and if no exact square root is found, leave it in the form of a square root symbol or as a decimal approximation.
Step-by-step explanation:
To change a decimal into surds, you need to express the decimal as a square root. This means finding a square root that is equal to the decimal. Here is a step-by-step process:
- Convert the decimal into a fraction if it isn't already.
- Simplify the fraction if possible.
- Find a square root equal to the simplified fraction.
- If no exact square root is found, you can leave it in the form of the square root symbol.
- If the fraction can't be simplified, you can leave it as a decimal approximation.
