WRONG ANSWER WILL BE REPORTED ​

Answer 1

Answer:

• C. k = 25

Step-by-step explanation:

Given :

• x³ - k when divided by x - 3 remainder is 2

To Find :

• Value of k

Solution :

Let f(x) = x³ - k

$\tt \to (x - 3) \\ \tt \to \: x - 3 = 0 \\ \tt \to \: x = 0 + 3 \\ \tt\to \: x = 3$

Now, put the value of x on x³ - k

$\bf f(3) = (3 {)}^{3} - k \\ \bf2 = 27- k \\ \bf \: k = 27 - 2 \\ \bf \: k = 25$

Thus, options c is correct k = 25

Answer 2

Answer:

right answer is 25

coz when we equate x-3 = 0 , x = 3

now put value of x in x^3-k

3^3-k = 2

27- k = 2

-k = 2-27

k = 25

thus 25 is ur required answer
