Question

Find the value of A and B in

$ab \\ \times b3 \\ = 57a$
with explanation
​

Answer 1

Step-by-step explanation:

$ab \times {b}^{3} = 57a \\ a {b}^{4} = 57a\: \: - - - (i)\\ divide \: both \: sides \: by \: a \\ {b}^{4} = 57 \\ b = \sqrt[4]{57} \\ b = {(57)}^{ \frac{1}{4} }$

It is impossible to find the value of a . I only can find the value of b . so I think this question is wrong .
