দুটি পদ হল, 8 + 4√2 এবং 6 - 3√2
ব্যাখ্যা:
দুটি সংখ্যার গুণফলের বর্গমূল (a & b) যখন সমানুপাতের গড় হিসাবে প্রকাশ করা হয়।
যেমন: a/x : x/b
গণনা:
ধরা যাক, 'x' হল গড় সমানুপাতিক মান।
(8 + 4√2) /x : x/( 6 - 3√2)
⇒ x2 = ( 8 + 4√2) x (6 - 3√2)
⇒ x2 = 48 - 24√2 + 24√2 - 24
⇒ x2 = 24
⇒ x = 2√6
∴ গড় সমানুপাতিক মান হল 2√6
