Two circles with centres A and B touch each other externally at point P. The distance AB is equal to:

The multiplicative inverse of 3 + 2i is:

Let f(x) = x² − 3x + 1. If Sₙ denotes the sum of the nth powers of the roots of f(x), then S₂ equals:

Let f(x) = ∫₀ˣ of e^(−t²)·cos(2t) dt. The value of f(x) as x approaches ∞ is

The distance of the point P(3, 4) from the origin is:

If z is a complex number such that |z − 3i| = 3, then the locus of z is:

From an external point P, a tangent to a circle with centre O is 24 cm long. If the distance of P from the centre is 25 cm, the radius of the circle is:
