FireYo:

what do you notice about this probelm

klmjnmkj:

im not sure

FireYo:

Ik it may look very confusing

snowflake0531:

You should know what e is, it's actually just an irrational number so put into your calculator e^-1.6, and round to the nearest 5th decimal point

Extrinix:

Actually, e is equal to 2.71828182846, not a variable

Extrinix:

so what does \(e^\text{-1.6}\) equal?

klmjnmkj:

0.20189651

Extrinix:

round to five decimal places.

FireYo:

Do you got it?

klmjnmkj:

ho do i round five decimal places

Extrinix:

you're correct, but you need to round to 5 decimal places

FireYo:

ok so u take the point and move it 5 times to the right

Extrinix:

incorrect

Extrinix:

to round five decimal places, count 5 decimal places from the .

FireYo:

or it might be the other way, left and right confse me

Extrinix:

\(0.20189651 \\ ~~~~~~~~~~\uparrow \\ \text{that is the fifth place, look at the number after,} \\ \text{that number is 6, look at the rules:} \\ \text{ } \\\text{1 to 5: keep the number} \\ \text{6 to 9: round up 1 (so if it's 5 it would be 6)}\)

@florisalreadytaken

snowflake0531:

we have 0.20189651799 what is the 6th digit to the right of the decimal point

klmjnmkj:

6

snowflake0531:

so 0.201896 Now because 5 or on, we round over, 9 goes up 1, but because 9 would become 10, we would round it straight to 0.202190 remember the 0 at hte end

klmjnmkj:

alright

klmjnmkj:

0.202190 is the anser?

snowflake0531:

wait oops

snowflake0531:

i accidentally added a 2 it's just 0.20190
