Surds 5x√2x is equivalent to √50x³ after it has been simplified completely.
What is surds in maths?
- When a square root, cube root, or other root symbol is used in an expression, it is known as a surd.
- Irrational numbers cannot be stated accurately in decimal form because their decimals do not finish or recur.
- Surds are used to write irrational numbers precisely.
For this case we have the following expression
√50x³
We can write it as
We know that
√25 = 5
By power properties we have
√x² = = x¹ = x
So simplifying we have
5x√2x
