Round off following number upto four significant figures.
The given number has significant figures.
As , thus the digit gets changed to after rounding off upto four significant figures.
After rounding off, becomes
To round the number 45.689 to four significant figures, we follow a systematic approach:
Identify the significant figures in the number. The number 45.689 has five significant figures: 4, 5, 6, 8, and 9.
Determine the fourth significant figure. In this case, the fourth significant figure is 8.
Look at the digit immediately following the fourth significant figure, which is 9. According to rounding rules, if this digit is 5 or greater, we round up the fourth significant figure.
Since 9 is greater than 5, we round the digit 8 up to 9. Therefore, the number becomes 45.69 when rounded to four significant figures.
