ఇచ్చినది:

రెండు పదాలు 8 + 4√2 మరియు 6 - 3√2

వివరణ:

నిష్పత్తి యొక్క అనుపాత రూపంలో వ్యక్తపరిచినప్పుడు రెండు సంఖ్యల (a & b) లబ్ధం యొక్క వర్గమూలం.

ఉదాహరణకు: a/x : x/b

గణన:

'x' సగటు అనుపాతం విలువగా ఉండనివ్వండి.

(8 + 4√2)/x : x/(6 - 3√2)

⇒ x2 = (8 + 4√2) × (6 - 3√2)

⇒ x2 = 48 - 24√2 + 24√2 - 24 

⇒ x2 = 24

⇒ x = 2√6

∴ సగటు అనుపాతం విలువ 2√6
