Question

What is the solution to the equation 1 over the square root of 8 = 4(m − 3)?

Answer 1

Given expression : √8 = 4 (m-3)


Solution : √8 = 4 (m-3)

=> 8 = {4 (m-3)}²

=> 8 = 16 (m-3)²

=> 8 - 16 = m²-6m+9

=> - 17 = m²-6m

=> m ( m - 6 ) = -17


Either, m = - 17

Or, m - 6 = - 17

=> m = -17+6

=> m = - 11
