Question

if a square b is equal to 27 and a b square is equal to 8 then find the value of a multi b is equal to what​

Answer 1

a²b= 27 (1)

ab² = 8 (2)

b= 27/a² [from 1]

put b= 27/a² in (2)

a(27/a²)²= 8

729/a³= 8

a³= 729/8

a= 9/2

Substitute the value of a = 9/2 in (1)

(9/2)²b =27

81b/4= 27

b = 27×4/81

b= 4/3

Now

a×b = (9/2)×(4/3)=6
