Exponents of variables are easily solved using:
x^2 or x^3

Example...

ncl 19> a = 5
ncl 20> b = a^2
ncl 21> c = a^3
ncl 22> print(a)

Variable: a
Type: integer
Total Size: 4 bytes
1 values
Number of Dimensions: 1
Dimensions and sizes: [1]
Coordinates:
(0) 5
ncl 23> print(b)

Variable: b
Type: float
Total Size: 4 bytes
1 values
Number of Dimensions: 1
Dimensions and sizes: [1]
Coordinates:
(0) 25
ncl 24> print(c)

Variable: c
Type: float
Total Size: 4 bytes
1 values
Number of Dimensions: 1
Dimensions and sizes: [1]
Coordinates:
(0) 125

Hope this helps!
