If x = 1/x-5 x ≠ 5, find : x²-1/x² |
|
Answer» Here you go mateStep-by-step explanation: x = 1 / ( x - 5 ) x -5 = 1 / x [since x is not equal to zero] LET x - 1 / x = 5 be (1)Squaring both sides ( x - 1 / x ) ^ 2 = 25 [ x^2 – 2x( 1/x ) + 1 ] / (x^2) = 25 x^2 – 2 + 1 / (x^2) = 25 x^2 + 1 / (x^2) = 25 + 2 = 27Adding 2 to both sides we have x^2 + 2 + 1 / (x^2) = 29 x^2 + 2x( 1/x ) + 1/( x^2 ) = 29 ( x + 1 / x )^2 = 29 Let x + 1 / x = (29) ^ ( 1/2 ) be (2)Multiplying (1) and (2) we have x^2–1/x^2=+-5×(29)^(1/2)Hope it helps.Please mark me a the BRAINLIEST. |

Express 45,39,64 as the sum of the two odd prime numbers |
|
Answer» Step-by-step explanation:(i) Co-PRIMES: Two natural numbers are said to be co-prime numbers if they have 1 as their only common FACTOR. Hence, all the given pairs of numbers are co-primes. (ii) Primes: Natural numbers which have EXACTLY two distinct factors, i.e., 1 and the NUMBER itself are called prime numbers. Hence, (59, 61) and (71, 73) are pairs of prime numbers. (iii) Composite numbers: Natural numbers which have more than two factors are called composite numbers. Hence, (55, 57) and (63, 65) are pairs of composite numbers.mark as brainly |
