Question

True or False type questions​

Answer 1

Hey...

71) False...as we have p&q with power 1 also

72) True

73) False... its factorisation is 3a(a+b+c)

74) True

75) Full Q is not visible

76) False......as it can not be solved further

77) True.....as it can also be written as p/3*p/3.....by changing division into multiplication

78) True.....51^2=2601, 49^2= 2401....on subtracting 2401 from 2601 we get 200......100*2=200....so p=2

79) True.....as 9 will be cancelled from numerator and denominator

80) True....as on solving the equation we would get (a^2)^2 - (1)^2 = a^4-1

Hope this helps...!!!
