Given: x² = y³.

Raising both sides to the power 3 gives: x⁶ = y⁹.

Therefore, x²ᶻ = x⁶, so 2z = 6 and z = 3.

Explanation

Rule:

If distance < radius → point inside → 0 tangent

If distance = radius → point on circle → 1 tangent

If distance > radius → point outside → 2 tangents

Here: Distance of Q = 7 cm, Radius = 4 cm

7 > 4, so Q is outside the circle, so 2 tangents can be drawn.
