${1.2}^{3} = 1.728$

#### Explanation:

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

${x}^{5} \times {x}^{-} 2 = {x}^{5 - 2} = {x}^{3} \text{ or } {x}^{5} \times {x}^{-} 2 = {x}^{5} / {x}^{2} = {x}^{3}$

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

${1.2}^{5} \times {1.2}^{-} 2 = {1.2}^{5 - 2} = {1.2}^{3}$

This can be calculated to give $1.728$
