If the cube root of square of x is the square root of cube of y, then the relation between x and y is
1). x3 = y2
2). x2 = y3
3). x4 = y9
4). x8 = y27
Given,
$(\sqrt[3]{{{x^2}}}\; = \;\sqrt[2]{{{y^3}}})$
⇒ x2/3 = y3/2
Taking LCM of 2 and 3 and multiplying that to the powers on both sides.
⇒ x4 = y9
∴ The relation between x and y is x4 = y91. If 70% of an equal to 40% of b, then ratio between a and b is?
