Best ResponseYou've already chosen the best response.0You have\[x^3 = \frac{ 1 }{ 8 }\] If you can express \(\frac{1}{8}\) as a number raised to exponent 3, then you can simply equate the bases. Can you think of a number that, when cubed, equals 1\8 ?

Best ResponseYou've already chosen the best response.0b is incorrect because the plus and minus sign you dont use in power to the third

Best ResponseYou've already chosen the best response.0Excellent. So\[x^3 = \left( \frac{ 1 }{ 2 } \right)^3\]When the exponents are the same, simply equate the bases. So\[x=?\]

Best ResponseYou've already chosen the best response.0We worked it down to\[x^3 = \left( \frac{ 1 }{ 2 } \right)^3\]Since exponents are the same we can equate just the bases, i.e.\[x=\frac{ 1 }{ 2 }\]See how that works?
