यदि `xsin45^(@)=yco s ec30^(@)` है तो `(x^(4))/(y^(4))` किसके बराबर है?

A

`4^(3)`

B

`6^(3)`

C

`2^(3)`

D

`8^(3)`

लिखित उत्तर

Verified by Experts

The correct Answer is:
a

`xsin45^(@)=y co s ec30^(@)`
`rArr(x)/(y)=(co s ec30^(@))/(sin45^(@))rArr(2)/(1//sqrt(2))rArr(2sqrt(2))/(1)`
`rArr(x^(4))/(y^(4))=((2sqrt(2))/(1))^ (4)rArr(64)/(1)`
`=4^(3)`
