if `sqrt(10+-2sqrt21) = sqrta+-sqrt3` then `a=`

If sqrt(10-2 sqrt 21)+ sqrt(8+2 sqrt 15)=sqrt a+ sqrt b , where a and b are positive integers, then the value of sqrt(ab) is closest to:

If sqrt(10-2 sqrt21)+ sqrt(8+2 sqrt15)= sqrta+ sqrt b , where a and b are positive integers, then the value of sqrt(ab) is closest to : यदि sqrt(10-2 sqrt21)+ sqrt(8+2 sqrt15)= sqrta+ sqrt b है, जहाँ a और b धनात्मक पूर्णाक है, तो sqrt(ab) का मान ( लगभग ) ज्ञात करें |
