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

Mathematics
1 answer:
sveticcg [70]3 years ago
7 0

Answer:

(C) 4

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

Finding the roots (zeros)
GenaCL600 [577]

Answer:

1.5 + 1.3228756555323i

1.5 - 1.3228756555323i

Step-by-step explanation:

y = ax^2 + bx + c

a = 1, b = -3, c = 4

Using the quadractic formula:

\frac{-b±\sqrt{b^2-4ac} }{2a} \\\\= \frac{3±\sqrt{9-4(1)(4)}}{2(1)}\\\\= \frac{3±2.64i}{2}\\\\= 1.5 ±  1.32

Note: Kindly ignore the A in the above solution ^

Hence, there is no real solution. It has complex roots.
