Evaluate:
`(6^4 xx 9^2 xx 25^3)/(3^2 xx 4^2 xx 15^6)`
उत्तर
We have, `(6^4 xx 9^2 xx 25^3)/(3^2 xx 4^2 xx 15^6) = ((2 xx 3)^4 xx (3^2)^2 xx (5^2)^3)/(3^2 xx (2^2)^2 xx (3 xx 5)^6)`
= `(2^4 xx 3^4 xx 3^4 xx 5^6)/(3^2 xx 2^4 xx 3^6 xx 5^6)` ......[∵ (a × b)m = am × bm]
= `2^(4-4) xx 3^(4+4-2-6) xx 5^(6-6)` ......`[∵ a^m/a^n = a^(m-n)]`
= 20 × 30 × 50
= 1 × 1 × 1
= 1
