Question

A.Write the expression 243^-2/5 in radical expression.
B.Evaluate the radical expression

Answer 1

your exponent is \(-\frac{2}{5}\) which has three parts
a numerator of 2 which is the power,
a denominator of 5 with means the fifth root
and a minus sign which means take the reciprocal

Answer 2

since \(243=3^5\) the fifth root of 435 is \(3\)
then \(3^2=9\) and the reciprocal of 9 is \(\frac{1}{9}\)

Answer 3

so the answer would be 243=\[3^{5}\] and \[\frac{ 1 }{ 9 }\]
