(3)/(sqrt(7)+2)

int(3)/(sqrt(7x-2)-sqrt(7x-5))dx=

(3)/(7+sqrt(2))=

Evaluate (sqrt(5)-sqrt(3))/(sqrt(2)+sqrt(7))

sqrt(2)+sqrt(3)+sqrt(7)-(1)/(sqrt(2)+sqrt(3)+sqrt(7))=?

The expression (sqrt(5)-sqrt(3))(sqrt(7)-sqrt(2)) when simplified becomes a

(sqrt(3)-sqrt(5))(sqrt(3)+sqrt(5))/(sqrt(7)-2sqrt(5))

If we reduce 3x+3y+7=0 to the form x cos alpha+y sin alpha=p, then the value of p is (7)/(2sqrt(3))( b) (7)/(3)( c) (3sqrt(7))/(2)( d) (7)/(3sqrt(2))

If we reduce 3x+3y+7=0 to the form xcosalpha+ysinalpha=p , then the value of p is 7/(2sqrt(3)) (b) 7/3 (c) (3sqrt(7))/2 (d) 7/(3sqrt(2))

Write the complex number: sqrt(3)/2-sqrt(-2)/7
