Answer:
27
Step-by-step 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
