Question

if x is equals to 2.14 and Y is equals to 3.232 then the value of x y taking into account significant figures will be​

Answer 1

Answer:

6.92

Explanation:

because resultant is number of decimal places least out of question

Answer 2

Answer:6.91

Explanation:

Let's have a look at the basic rules of significant figures so that we can find out the answer of our problem without any problem.

A sufficient number of significant data is important to have meaningful power when reporting analytical concentrations. Various methods or parameters can be used to determine the number of significant digits required. In most cases, 3 metrics are sufficient.

There are certain rules that must be followed to measure the significant digits of the calculated measurements. The basics of the

rule are:

• Any non-zero number is valid.
• zeros between non-zero digits are valid.
• Only trailing zeros or decimal trailing zeros matter.

To determine the number of significant digits, use the following three rules:

• Non-zero digits are always valid
• All zeros between two significant digits are valid
• Only trailing zeros or trailing zeros in fractional part are valid

Example: .500 or .632000 Zeros are valid

.006 or .000968 Zero is not valid

Use the following rules for addition and subtraction:

• Addition problem or subtraction in the usual way
• The final answer is any number of the problem There must be no more significant digits to the right of the decimal point than the minimum number of significant digits.

Use the following rules for multiplication and division:

• The minimum number of significant digits for any number of problems determines the number of significant digits for the solution. (whole numbers are displayed as well as fractional parts)
• *This means you must be able to recognize valid numbers to use this rule*

In the question x=2.14 and y=3.232 hence xy=2.14*3.232=6.91648

but in the value of x only 3 significant figures are there and in y 4 significant figures are present and according to the rules of significant figures "The minimum number of significant digits for any number of problems determines the number of significant digits for the solution." which means in the final only 3 significant figures can be there hence final answer will be 6.91
