Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m
Dmitry_Shevchenko [17]

Answer:

\ln{(z)}+2\ln{(z-1)}

Step-by-step explanation:

\ln{(z(z-1)^2)}

we know that

  • \ln{ab} = \ln{a}+\ln{b}

\ln{(z)}+\ln{(z-1)^2}

we also know that:

  • \ln{a^b} = b\ln{a}

\ln{(z)}+2\ln{(z-1)}

and this is our logarithmic expression rewritten!

Help i have no idea how to solve this
ASHA 777 [7]

Answer:

AB =24

Step-by-step explanation:

So, since all the sides are equal, you can just take two of the sides and set em equal to each other to find x and then, solve for AB

4x+8 =6x

8= 6x-4x

8=2x

8/2 =x

x= 4

Now, find AB, which is 4x+8

4(4) + 8

16+8 = 24

Hope this helps!

Please mark brainliest if you think I helped! Would really appreciate!

Find the area of the circle with a circumference of 50.24 units help me plz
swat32
Circumference of a circle=diameter times pi

50.24=d(3.14)
d=16

radius is half of diameter so radius is 8

Area of a circle=pi(r^2)

(3.14)(8^2)=(3.14)(64)=200.96
