Question

State with reason, whether the following is a surd and which is not?

`6sqrt(16)`

Answer 1

Not Surd

Reason:

Given: `6sqrt(16)`

Step-wise calculation:

1. Simplify: `sqrt(16) = 4`
2. Multiply: 6 × 4 = 24

Since the expression `6sqrt(16)` simplifies to 24, which is a rational number (not irrational), it is not a surd.
