Answer:

27

Explanation:

Step-by-step explanation:

Breaking 9^3\2

down into its component parts3\2

is the same as

3× 1/2

which is the same as

1/2×3

so

9^3\2

is the same as

(9^1\2)×3

Write this as:

(9^1\2)3

Consider the part of

9^1\2

This is the same as

√9=3

So

(9^1\2)3=(√9)3

=3^3=27

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

However, it true to say that:

√9=± 3

and

(±3)3 =± 27
