2.072539 rounded to the nearest hundredth

2.07

Step-by-step explanation:

The reason for that is if the thousandths place was greater that 5 it will change the 7 to an 8

so when rounding the number will change if it is greater than 5

if  less than it will stay the same and the rest will become 000 after it

2.07000 but  an easier way to say it is 2.07

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
