Question

if (x -)=10,find the value of the (x²+) and (x⁴+)​

Answer 1

Answer:

X+1/x = 5

(x+1/x)² = x²+1/x²+2

(5)² = x²+1/x²+2

25-2 = x²+1/x² => 23

(x²+1/x²)² = x⁴+1/x⁴+2

(23)² = x⁴+1/x⁴+2

529-2 = x⁴+1/x⁴

527 = x⁴+1/x⁴

Answer 2

Answer:

Given - (x-) = 10

To find- x^2

x^ 4

Solution -

putting value of x in x^2

(10 )^2

10 × 10

100

putting value of X in x^10

( 10)^10

10 × 10 × 10 × 10 .......

1000000000

Note - there is something wrong in the que. it is either plus 10 or minus 10 but not x minus .
