No worries. It’s just that without being told, one can’t know what the root is without also knowing what the exponent is.
If it was 32^.75 this wouldn’t be something to the 5th root, right? It’d be (4√32)^3 Just remember to turn the decimal into a fraction, simplify it, and the denominator (bottom part) is the root, while the numerator (top part) is the exponent.
.75 = 3/4 (which is already simplified), so it’s 32 to 4th root cubed (^3)
