`(18)/(126) xx 360`

5 boys and 5 girls are siting in a row randomly . The probability that boys and girls sit alternatively is : a) (5)/(126) b) (1)/(126) c) ( 4)/(126) d) (6)/(126)

sqrt((324)/(49))xx sqrt((676)/(169))xx(126)/(sqrt(81))=x

((?)/(18)) xx ((?)/(162))=1

Find the product: (-18) xx (-5) xx (-4)

18/11 xx (-33)/45

(-105)/72 xx 18/15

(679)/(45)div(23)/(2130)xx(126)/(169)=?

If x= (sqrt126 xx sqrt63 xx sqrt45)/(sqrt147 xx sqrt243) , then the value of x is
