Question

Find each value of e^x to four decimal places:

A. e^10 which = e^(10)

B. (1/e^3)^2

(1/(e^3))^2 =

Answer 1

Unless your school does not allow the use of calculators, in which case a table of logarithms will be supplied, I will assume that the use of calculators is permitted.
Most modern scientific calculators have the functions required to calculate the values above to 8 or 10 figures of accuracy. I will present the answers to 2-3 figurs of accuracy for you as a check.
If you have difficulties, or if calculators are not permitted, please post again.

A. e^10 which = e^(10)
If you have a TI algebraic calculator, press 10 and the buttins (2nd) and LN which is equivalent to e^x.
You should get
e¹⁰ = 22026.xxxx

B. (1/e^3)^2
(1/e^3)²
= (e^-3)²
= e^-6
= 0.00xx

Answer 2

I got the answer to the first one. I finally figured out how to use that function. Thanks! NOW what about that second one? How do I punch in the numbers for this one? Thanks!

Answer 3

You do the same thing, except replace 10 with -6, something like
6 +/- (2nd) LN

Answer 4

Got it thanks!

Answer 5

Great!
