If X=4+√15,then find the value of [x+1 upont x]

Answer» HEYA !!



X = ( 4 + ✓15 )




1/X = 1 / (4 + ✓15 )




1/X = 1/ ( 4 + ✓15 ) × ( 4 - ✓15 ) / ( 4 - ✓15 )





1/X = ( 4 - ✓15) / ( 4 + ✓15 ) ( 4 + ✓15 )




1/X = ( 4 - ✓15 ) / (4)² - (✓15)²


1/X = ( 4 - ✓15 ) / 16 - 15




1/X = ( 4 - ✓15 )/1



1/X = ( 4 - ✓15 )




Therefore,




X + 1/X = ( 4 + ✓15 ) + ( 4 - ✓15 )





X + 1/X = 8.

Solve Q1 step by step in copy

Answer»

If the POLYNOMIALS az³ + 4z² + 3z - 4 = 0 and z³ - 4Z + a = 0 leaves the same REMAINDER when divided by z - 3, FIND value of a

z - 3 = 0
z = 3

substitute z in both polynomials
both polynomials leaves same remainder so equate both equation
so,
a(3)³ + 4(3)² + 3(3) - 4 = (3)³ - 4(3) + a
27a + 36 + 9 - 4 = 27 - 12 + a
27a + 41 = 15 + a
27a - a = -41 + 15
26a = - 26
a = -1

If one root of the equation2x^2-ax+64 is twice the other,find the value of a

Answer»

Heya !!



P(X) = 2X² - AX + 64



Here,



COEFFICIENT of X² = 2


Coefficient of X = -A


And,


Constant term = 64




Let one zero of the given quadratic polynomial be Alpha .



Other zero = 2Alpha




THEREFORE,

PRODUCT of zeroes = Constant term/Coefficient of X².



Alpha × 2Alpha = 64/2



2Alpha² = 32


Alpha² = 16



Alpha = ✓16 = (+4) or (-4)



And,


Sum of zeroes = -(Coefficient of X)/Coefficient of X²




Alpha + 2Alpha = -(-a)/2



4 + 2 × 4 = a/2




4 + 8 = a/2





a = 12 × 2



A = 24 .

If a=b^x,b=c^y and c=a^z then find the value of xyz

Answer»

A=B^x
by taking log we get,
log a= log(b^x) {as, log (m^n)=n log m}
=x log b
or, x= (log a)/ (log b)

similarly, y=(log b)/(log c)
and Z= (log c)/(log a)

thus,
XYZ
=(log a× log b× log c)÷(log a×log b× log c)
=1
