Question 254529
{{{(root(5, 2x^6y))^7}}}
Radicals can we rewritten using fractional exponents. 5th roots, like this one, can be replaced with an exponent of 1/5:
{{{((2x^6y)^(1/5))^7}}}
Now we can use the rule for exponents, {{{(a^p)^q = a^(p*q)}}}:
{{{(2x^6y)^(7/5)}}}
Raising each factor to the 7/5 power:<br>

{{{2^(7/5)x^(42/5)y^(7/5)}}}
If you can't read the exponents, they are:
7/5, 42/5, and 7/5
