Question

Solve This!!! And Explain It!!!!! Itz Hard!!

Answer 1

Answer:

I think ,,answer will be 40

Step-by-step explanation:

because the interval between the first and two is 6 numbers,,and the interval between the two and third is 12 so next will be 18 by the following of 6 table

Answer 2

   a + b + c = 4  ....eqn (1)

   a² + b² + c² = 10  ....eqn(2)

   a³ + b³ + c³ = 22  .....eqn(3)

To find :-

a⁴ + b⁴ + c⁴ = ?

Solution :-

As given ,equation (1)

a+b+c= 4

After squaring both sides

(a+b+c)² = 4²  {Use the identity (x+y+z)² = x² + y² + z² + 2 ( xy + yz + xz)}

a²+b²+c²+2(ab+bc+ca)= 16 {as 4² = 16}

10+2(ab+bc+ca) = 16 {Now take 10 on the other side}

2(ab+bc+ca)= 6  {Now take 2 on the other side}

ab+bc+ca= 3

At last a^4+b^4+c^4 = 1350
