Question

If x=(5-3)/21 find the value of (x^3+1/x3)-5(x^2+1/x^2)+(x+1/x)​

Answer 1

Answer:

$= (5 + 3).00 + 13 < y {8}^{9} = 7.7 |7| \beta \% \sec(8888) = xx {9}^{2} \sqrt[7]{ - \times 23 = i dont \: know$

Use the sqerot of 7 divide it by times 2 equals 0 to the nerest 2 use the formula to get tge mean median and mode trough social distance from Xx corovid69 x3 *= Number

Answer 2

Step-by-step explanation:

x=2/21

((2/21)^3+(1/(2/21)^3))-5((2/21)^2+(1/(2/21)^2))+(2/21+(1/(2/21))

=1157.625864-0.045351473+110.25+10.5952381

=1278.425751
