No, a lone variable has an invisible one in front of it, So 4z (can’t put the top number sorry) So 4z - z would equal 3z
Answer:
b =± 5 sqrt(3)
Step-by-step explanation:
f(b) = b^2 – 75
To find the roots set the equation equal to zero
b^2 -75 =0
Add 75 to each side
b^2 – 75+75 = 0+57
b^2 = 75
Take the square root of each side
sqrt(b^2) = ±sqrt(75)
b = ±sqrt(3*25)
We know that sqrt(ac) = sqrt(a) sqrt(c)
b = ±sqrt(3)*sqrt(25)
b =± 5 sqrt(3)

Answer:
Option: C is correct.

Step-by-step explanation:
We are asked to solve for 'x' such that we are given a equation as:

This equation could also be written as:

on taking logarithmic function on both the sides we have:

(since
)
as we know 
Hence, we have: 
Hence, option C is correct.
