In the following equations, find which variables x, y, z etc, represent rational or irrational numbers : (i) x2 = 5 (ii) y2= 9 (iii) z2 = 0.04 (iv) u2=174 (v) v2 = 3 (vi) w2= 27 (vii) t2=0.4

Answer»

In the following equations, find which variables x, y, z etc, represent rational or irrational numbers :

(i) $x^{2}$ = 5 (ii) $y^{2}$ = 9

(iii) $z^{2}$ = 0.04 (iv) $u^{2} = \frac{17}{4}$

(v) $v^{2}$ = 3 (vi) $w^{2}$ = 27

(vii) $t^{2} = 0.4$
