1.2^3 = 1.7281.23=1.728

Explanation:

We would do this in exactly the same way as if we we had variables.

x^5 xx x^-2 = x^(5-2) = x^3" or "x^5 xx x^-2 = x^5/x^2 = x^3x5×x−2=x5−2=x3 or x5×x−2=x5x2=x3

If the bases are the same and you are multiplying, ADD the indices.

1.2^5 xx 1.2^-2 = 1.2^(5-2) = 1.2^31.25×1.2−2=1.25−2=1.23

This can be calculated to give 1.7281.728
