Question

If x+1/x=3 then x^6+1/x^6​

Answer 1

Step-by-step explanation:

x+x1=3x3 +x31+3(x+x1)=27x 3+x3

1 =27−9=18 (x3+x31)

2=(x6+ x 61 +2)

Now, x6+ x 61+2=324x 6 + x 6

1=322

Hope its help..

Answer 2

Solution :

$\: \: \: 15x + 45 = 100$

$= > 15x = 100 - 45$

$= > 15x = 55$

$= > x = \frac{55}{15}$

$= > x = \frac{11}{3}$

$= > x = 3.67$
