Answer 2

Answer:

The required answer is 1.780.

Step-by-step explanation:

Significant figures:-

• The number of digits in a value that contribute to the accuracy of the value is called significant figures.

Rules of significant figures:-

• All digits except the number 0 are always significant.
• Any zero placed in between any tow non-zero digits are significant.
• Zeros placed at left of a non-zero digit and right of a decimal point are not significant.

According to the question,

The given number is 1.7802.

We need to round off the number to the one significant figure.

Since the number 1.7802 consists of 5 significant figures.

Then,

Rounding the given number to 1 significant figure is,

1.7802 ≈ 1.780

Therefore, the required answer is 1.780.
