3 3/6 is the same as 3 1/2, so 23 take 3 is 20. 20 take 1/2 is 19 1/2.
Answer:
Yes, the both sides of the given equation are equal.
Step-by-step explanation:
The given equation is
Taking LHS,
Using the power property of logarithm, we get
![[\because log_ax^n=nlog_ax]](https://tex.z-dn.net/?f=%5B%5Cbecause%20log_ax%5En%3Dnlog_ax%5D)
![[\because RHS=3\log(1-i)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20RHS%3D3%5Clog%281-i%29%5D)
Both sides of the given equation are equal.
Answer:
C and D
Step-by-step explanation:
Mathematically, a unit circle is one in which the value of the radius is 1 unit
Generally, for a unit circle we have it that;
r^2 = x^2 + y^2
where (x,y) represents the coordinates of a point on the unit circle
But from above, r = 1
Thus:
x^2 + y^2 = 1
Looking at option C, by squaring each coordinate, we have
(6/7)^2 = 36/49 and the second as 13/49
by adding both, we have
36/49 + 13/49 = 49/49 = 1
Thus, we have this as a coordinate on the unit circle
For the last option;
(5/13)^2 = 25/169 and (12/13)^2 = 144/169
Adding both, we have;
25/169 + 144/169 = 169/169 = 1
So this is also a point on the unit circle
