प्रश्न
The square root of `(256x^8y^4z^10)/(25x^6y^6z^6)` is equal to
विकल्प
`16/5|(x^2z^4)/y^2|`
`16|y^2/(x^2z^4)|`
`16/5|y/(xz^2)|`
`16/5|(xz^2)/y|`
उत्तर
`16/5|(xz^2)/y|`
Explanation;
Hint:
`sqrt((256x^8y^4z^10)/(25x^6y^6z^6)) = sqrt(256/25 xx (x^(8-6) xx z^(10-6))/y^(6 - 4)`
= `sqrt(256/25 xx (x^2z^4)/(y^2)`
= `16/5|(xz^2)/y|`
