A surd is when you have a number that is irrational or in other word, A number that its number cannot be square rooted e.g. A square root of 2,3,5 etc, on the other hand an indices are numbers that are cubed or squared for instance 3³ ('3 cubed' or '3 to the power of 3') and 5² ('5 squared' or 5 'to the power' of 2) are example of numbers in index form.
3³ = 3×3×3
2¹ = 2
2² = 2×2
2³ = 2×2×2
etc.
The ² and ³ are known as indices. Indices are useful (for example they allow us to represent numbers in standard form) and have a number of properties.
'Indication' is the noun form of the verb form 'indicate' while indicative is the adjective form of the same verb form. An adjective describes the thing with which it is used.

Is pi a surd?
No.
What is an infinite surd?
Infinite surd is a term used in mathematics. The definition of an infinite surd is a never ending irrational number with an exact value that would be left in square root form.
How do you simplify a surd in the form A square root B?
A surd in the form a√b cannot, in general, be simplified.
Is every irrational a surd?
Normally they are.
Is square root of 8 a surd?
yes
What does the amount of refraction depend on the two materials?
The amount of refraction that occurs at the interface between two materials depends on the difference in their refractive indices. A greater difference in refractive indices between two materials will result in a larger amount of refraction.
What determines how much of the light reflects on a boundary?
The amount of light that reflects on a boundary is determined by the difference in refractive indices between the two mediums the light is traveling through. A greater difference in refractive indices results in more light being reflected. This is described by the law of reflection.
Is 5 a surd?
Yes it is a surd
What is a square root of surd?
If the value of the surd is positive, then it will be another surd. Otherwise it will be a complex number.
Why pi is not a surd?
A surd is the square root of an integer (whole number), e.g. square root of 2 is a surd. Pi is not the square root of an integer so not a surd, just an irrational number
Cube root of 7 is a surd but is cube root of negative seven a surd?
I am pretty sure that the cube root of negative seven is a surd. I checked on the calculator.......and it showed a negative number.....??I think when it is not a surd...it's supposed to say error, so the number probably means that it is a surd..
Is there a law that you divide the surd index of a surd with a real no?
No. It is not a criminal or civil offence!
Is pi a surd?
No.
