Question

X square plus 1 / x square equals 93 find the value of x cube plus 1/ x cube

Answer 1

Step-by-step explanation:

x² + 1/x² = 93

(x² + 1/x² + 2) -2 = 93

(x + 1/x)² = 95

x + 1/x = (95)½

घन करने पर

(x + 1/x)³ = 95(95)½

x³ + 1/x³ + 3x(1/x)(x + 1/x) = 95(95)½

x³ + 1/x³ + 3 *(95)½ = 95(95)½

x³ + 1/x³ = 92(95)½
