x varies inversely as square of y . given that y = 3 for x = 1 . the value of x for y = 4 will be equal to :
"explanation : solution : given x = k / y ^ 2 , where k is constant . now , y = 3 and x = 1 gives k = 9 . . ' . x = 9 / y ^ 2 = > x = 9 / 4 ^ 2 = 9 / 16 answer : e"
divide(multiply(1, power(3, const_2)), power(4, const_2))
