Using the index law
![a^{ \frac{m}{n}} = (\sqrt[n]{a} )^m](https://tex.z-dn.net/?f=a%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%20%20%28%5Csqrt%5Bn%5D%7Ba%7D%20%29%5Em)
![\sqrt[3]{6859}=19](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B6859%7D%3D19%20)
, so we can also write this as
![( \sqrt[3]{19^3} )](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B3%5D%7B19%5E3%7D%20%29)
Answer: TRUE
Answer:
76° is the other one
Step-by-step explanation:
nope, no precise calculation here. the option are thankfully enough apart that solving it graphically is just fine. look at the screenshot. the upper intersection is the one with the 7° angle
the lower one is somewhat less than 90° :P
Answer:
x<4
Step-by-step explanation:
The graph is not ending therefore X can be only lower than 4. -4 wouldn't be considered to be in the answer as it is a value of x itself. Also, X can't be greater than 4 because 4 is the starting point of the graph. So the X is always lower than 4 and can equal -4. So it would be x<4.
hope that helps!
Step-by-step explanation:
x² + 20 = 2x
x² − 2x + 20 = 0
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-2) ± √((-2)² − 4(1)(20)) ] / 2(1)
x = [ 2 ± √(4 − 80) ] / 2
x = [ 2 ± √(-76) ] / 2
x = [ 2 ± 2i√19 ] / 2
x = 1 ± i√19
Answer:
exact form x = 2/e^2 decimal form is x = 0.27
