Question

Hello, I would like to receive help with surds question:

 

'5√5 can be written in the form 5^k

 

Find the value of k.'

 

Thank you in advance.

Answer 1

is this the problem ? ⁵√5

if so you want the fifth root of 5

⁵√5=5^k means k=1/5

if you had ²√3, you would write 3^(1/2)  (but you really don't need the 2 in ²√3)
