^4 sq rt of 256x^16 y^28
I'm guessing this means you want the 4th root? (square root of the square root)?
If so:
We know (or can use a calculator) that the 4th root of 256 is 4, since 4^4 = 4*4*4*4 = 64*64 = 256
To take the 4th root of exponential variables, divide the exponent by 4:
x^16 becomes x^4, and y^28 becomes y^7
Putting it all together:
4x^4y^7
