bazaltina [42]

Answer:

Problem 9:  -1/2

Problem 10:  1/5

Step-by-step explanation:

Problem 10:  Label the given ln e^(1/5) as y = ln e^(1/5).

Write the identity e = e.  Raise the first e to the power y and the second e to the power 1/5 (note that ln e^(1/5) = 1/5).  Thus, we have:

e^y = e^(1/5), so that y = 1/5 (answer).


Problem 9:    Let y = (log to the base 4 of) ∛1 / ∛8, or

                            y = (log to the base 4 of) ∛1 / ∛8, or

                             y = (log to the base 4 of) 1 /2

Write out the obvious:              

                            4                                   =   4

Raise the first 4 to the power y and raise the second 4 to the power (log to the base 4 of) 1 /2.  This results in:

                              4^y    =     1/2.  Solve this for y.  

                                 Note that 4^(1/2) = 2, so that 4^(-1/2) = 1/2

Thus, y = -1/2

Use long division to determine the decimal equivalent of fraction with numerator 2 and denominator 3. 0 point 6 bar 0 point 7 ba
VikaD [51]

Answer:

The correct answer is A

0.\bar6

Step-by-step explanation:

We want to determine the decimal equivalence of \frac{2}{3}.


We perform the long division as shown in the attachment.


Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is 2, will be inside the long division sign.

We see that the quotient of our long division is 0.6666....


We can rewrite this as 0.\bar6


Therefore \frac{2}{3}=0.\bar6.
