Not a Hint: any value to the power 0 = 1 for example 3^0 = 1

OpenStudy (welshfella):

replace x by 0 in your function and what do you get?

OpenStudy (anonymous):

0

OpenStudy (welshfella):

e^0 = 0 ?

OpenStudy (anonymous):

idk

OpenStudy (welshfella):

3^0 = 1 so e^0 = 1 right - anything value to the power 0 = 1

OpenStudy (welshfella):

but here we have 7 ^ e^0 = ?

OpenStudy (anonymous):

7

OpenStudy (michele_laino):

hint: \[\Large f\left( x \right) = {e^x}\] is a continuous function, at all points of its domain, so we have: \[\Large \mathop {\lim }\limits_{x \to 0} {e^x} = {e^0} = 1\]

OpenStudy (welshfella):

yes

OpenStudy (anonymous):

so 7 is the answer

OpenStudy (welshfella):

yes
