Answer:
Step-by-step explanation:
We have to write 243 as a power of some number.
So, if we factorize 243 we get,
243 = 3 × 3 × 3 × 3 × 3
Therefore, we can write 243 as a power of 3.
No other number can be written in powers of 243 because it do not contain any other factor than 3.
Hence, 243 can be written as :

1. Write down the decimal divided by 1
2. Multiply both top and bottom by 10
3. Simplify the fraction.
First we must divide 9 by 3.
9/3 = 3
Then multiply it by 8
3*8 = 24. Hope this helps!
