1) a) From the set {-5, 3+4i, 0.25, 6, ½ , √(-49), √2, 3i, -1/5, 8, √7}
i) List the set of Natural Numbers
ii) List the set of Rational Numbers
iii) List the set of Irrational Numbers
vi) List the set of Real Numbers
b) Calculate
i) 6 x (-4) - (-17 + 8) + 6 x (-3) = ii) -6(-4) - 3(-5) + 3(-3) =
5(-4)+ (-2)7 - 8(-4)
I)
Natural numbers include all the whole numbers excluding the number 0
{6}
II)
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero
{-5, 0.25, 6, ½ , -1/5, 8}
III)
an irrational number cannot be expressed in the form of fractions
{√2,√7}
IV)
Real numbers are the numbers that include both rational and irrational numbers.
{-5, 0.25, 6, ½ , , √2, -1/5, 8, √7}
