If `y=x^n ,` then the ratio of relative errors in `y and x` is (a) `1:1` (b) 2:1 (c) 1:n (d) n:1

Explanation

To solve the problem, we need to find the ratio of the relative errors in \( y \) and \( x \) when \( y = x^n \).

### Step-by-Step Solution:

1. **Define the relative errors**:
- The relative error in \( y \) is given by:
\[
\text{Relative Error in } y = \frac{\Delta y}{y}
