Question 16 (1 point) (07.02)
What is the solution of log4x − 1032 = 5? (1 point)

a
x = −2

b
x = 2

c
x = 3

d
x = 4

x = 3.

Explanation:

The expression is miswritten.

I am going to try to show it correctly writen  using the math editor:

Just to be sure that it is understandable, the expression is read: logarithm base (4x - 10) of 32 equals 5.

To solve it, you take antilogarithm:

[4x - 10]^5 = 32

Now decompose 32 in 2^5

=> [4x - 10]^5 = 2^5

=> 4x - 10 = 2

=> 4x = 12

=> x = 12 / 4 = 3

x = 3

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
