let the tangent to the curve x1/2+y1/2 =a1/2 at any point on it cuts the axes OX and OYat P and Q respectively .hen OP+OQ =?

1.a

2.2a

3.a/2

4.a*a

  • 0

to find x, put y=0

then √x = √a

x = a

to find y, put x = 0

√y = √a

y = a

since we want to find OP + OQ, which is actually OP is x OQ is y.

so; x + y = a + a = 2a

answer is (b) 2a.
