express as power notation 32/243​

Answer 1

As 243 has 3 as its unit digit, 243 will not be divisible by 2. The sum of digits of 243 is 9 which is divisible by 3, so 243 is divisible by 3. We will now divide 243 continuously by 3. ∴−32243 is written as −(25)5 in power notation.

Answer 2

$\frac{32}{243} = \frac{2 \times 2 \times 2 \times 2 \times 2}{ 3 \times 3 \times 3 \times 3 \times 3} = \frac{ {2}^{5} }{ {3}^{5} } = { (\frac{2}{3} })^{5}$
