I don't understand the expression as the text you have given.
"the nth root is 4square root of 5 times the nth root is 4 square root of 5"
Is this exactly as presented in the question you were given?
im studying radicals and im having trouble....i need help on this one....i really don't know how to write but here it goes...
the nth root is 4square root of 5 times the nth root is 4 square root of 5...i need to simplify the expression

i don't know how to write it....its square root of 5 with the 4 on the left side times the square root of 5 with the 4 on the left side
OK
4sqrt5 x 4 sqrt5
another way to write this (struggling with the limits of text only!) is
5^(1/4)x5^(1/4)
(^ means to the power of so 10^2=100)
or 5 to power quarter x 5 to power quarter.
When you multiply two numbers with powers together you add the powers.
e.g. 10^2 x 10^2 = 10^4
or 100^(1/2) x 100^(1/2)=100^1 (or =100)
so
5^(1/4)x5^(1/4) =?
Does this help?

so the answer would be 5^1/2....is that right???
Yes
