Question

I Simplify: (1 by 3cube ) whole7

Answer 1

Answer:

The required simplified form is \dfrac{1}{3^{21}}

Step-by-step explanation:

Since we have given that

(\dfrac{1}{3^3})^7

So, we need to simplify it:

So, it becomes,

\dfrac{1}{(3^3)^7}\ (\because (\dfrac{a}{b})^m=\dfrac{a^m}{b^m})\\\\=\dfrac{1}{3^{21}}\ (\because (a^m)^n=a^{mn})

Hence, the required simplified form is \dfrac{1}{3^{21}}
