(a)

Interpretation Introduction

Interpretation:

The significant figures should be identified given the four different measurement values.

Concept Introduction:

Significant figures: The term significant figures refer to the number of important single digits in the co-efficient of an expression in scientific notation (for example 0 to 9 inclusive). The number of significant figures in an expression indicates the confidence or precision with which a scientist or engineer states a quantity.

In other words precision of measurements, the value recorded should use all the digits known with certainty, plus one additional estimated digit that is usually considered uncertain by plus or minus one it should be written as $(\pm 1)$.

Rounding value: (Rule 1) These terms explained corresponding values removes is four or less, drop it and all following digits.

Rule 2: If the first digit remove is five or greater, rounded the number up by adding a 1 to the digit to the left of the one may drop.
