Which of the following is true regarding the solution to the logarithmic equation below?
log2(x+11)=4
X+ 11 = 24
X+ 11 = 16
X=5
X= 5 is not a true solution because logs (16) 2
X= 5 is not a true solution because logs(16) 4
X= 5 is a true solution because log (16) - 4
X= 5 is a true solution because log (16) = 2

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
