What is the simplified form of ⁷√x ∙ ⁷√x ∙ ⁷√x ∙ ⁷√x A. 4⁷√x
B. x^4/7
C. ⁷√4x
D. x^7/4

I'm not 100% bur C. seems to make the most sense to me because your taken the seventh root of x 4 times so

I hope this is what you wanted:

b

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
