" (iii) "root(8)((x^(13))/(y^(21)))

Which of the following rational numbers are equal? (i) (-7)/(21) and 3/(-9) (ii) (-8)/(-14) and (13)/(21)

Numbers of real roots of ((5)/(13))^(x)+(21)/(13)=2^(x)

Divide: (i) (-16)/(21)\ b y4/3 (ii) (-8)/(13)\ b y3/(-26)

Divide: (-16)/(21)\ b y4/3 (ii) (-8)/(13)\ b y3/(-26)

If 3 - sqrt(2) is a root of x^(4) - 8x^(3) + 21x^(2) - 26x + 14 = 0 then the roots are

Solve for x and y in (13)/(x-3)-(6)/(y+1)=19;(21)/(x-3)+(11)/(y+3)=10
