How do you express 1/39 as an expression using a negative exponent other than -1? (i.e. Not 39^-1)

# 6.245^-2 (3dp)#

#1/39 =1/(sqrt39)^2 = (sqrt39)^-2 = 6.245^-2 (3dp)#[Ans]

#2xx78^-1#

I can only make sense of this by writing with a negative exponent and creating an equivalent fraction.

#1/39xx2/2=2/78=2xx78^-1#

#"or " 1/39=1/(3xx13)=1/3xx13^-1#

Should this not be necessary, please contact me again.
