If (NN)^3 = 8518N, what digit does N represent?

sveticcg [70]

Answer:

Step-by-step explanation:

I am going to solve this by trial and error:

(A) 1

Is: $(11)^{3} = 85181$ ?

$(11)^3 = 1331$

So 1 is not the digit of N.

(B) 2

Is: $(22)^{3} = 85182$ ?

$22^3 = 10648$

So 2 is not the digit of N.

(C) 4

Is: $(44)^{3} = 85184$ ?

$44^3 = 85184$

Correct, so the answer is c.

(D) 5

$55^3 = 166375 \neq 85185$

(E) 6

$66^3 = 287496 \neq 85186$
