Which expressions are equivalent to the one below? Check all that apply. log 2-log 6 A. log(2)+log(1/6) B. log 2 C. log 3 D. log(1/3)

option D is correct Log(1/3)

Step-by-step explanation:

Log2-Log6

Log(2/6)

Log(1/3)

this is false ^.^ lol

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
