b − 3 = 216 1 b 3 1 = 216 1 b 3 1 = 6 3 1 b 3 = 6 3 b = 6
if b^-3=1/216 find the reciprocal (^-1) of each side so it will be b^3=216 and then find the cube root so b=∛216 which is 6
The value of b that solves the equation b − 3 = 216 1 is 6 . To find this, we rewrite the equation, take reciprocals, and then deduce that b = 6 from the cube root of both sides. Thus, b = 6 is the solution.
