(12)

we are given

log_2(9x)

we can also write it as

log_2(9x)=log_2(9*x)

now, we can use property of log

log_2(9x)=log_2(9)+log_2(x)...........Answer

(13)

log_3(\frac{x^4y^8}{2} )

we can use property of log

log(\frac{a}{b})=log(a)-log(b)

log_3(\frac{x^4y^8}{2} )=log_3(x^4y^8)-log_3(2)

we can use property of log

log(a*b)=log(a)+log(b)

log_3(\frac{x^4y^8}{2} )=log_3(x^4)+log_3(y^8)-log_3(2)

log(a^n)=n*log(a)

log_3(\frac{x^4y^8}{2} )=4log_3(x)+8log_3(y)-log_3(2)...........Answer

(14)

log_2(11)-log_2(z)

we can use property of log

log(\frac{a}{b})=log(a)-log(b)

we get

log_2(11)-log_2(z)=log_2(\frac{11}{z}).............Answer

viktelen [127]

Answer:

Solve for the variable in the following equation: 1 / 6c + 1 / 3 = - 2
tankabanditka [31]

Answer: C. C=-14

Step-by-step explanation:

Given

(1/6)c+1/3=-2

Multiply both sides by the LCM of 1/6 and 1/3(Least Common Multiple)

6[(1/6)c+1/3]=(-2)(6)

c+2=-12

Subtract 2 on both sides

c+2-2=-12-2

c=-14

Hope this helps!! :)
