#root(3)(5) = 1.70997594668#

Explanation:

If both the denominator and numerator are raised to the same exponent, it can be rewritten outside of the fraction because it will get distributed anyways.
[It may not make sense right now, so see numbers below.]

#70^(1/3)/14^(1/3)# = #(70/14)^(1/3)#

A fractional exponent can be rewritten as a root and exponent.
denominator #-># root
numerator #-># exponent

[It may not make sense right now, so see numbers below.]

#(70/14)^(1/3)# = #(root(3)(70/14))^1#

Simplify #(70/14)#.

#(root(3)(70/14))^1 = (root(3)(5))^1#

Anything to the first power is itself.

#(root(3)(5))^1 = root(3)(5)#

Answer: #root(3)(5) = 1.70997594668#
