Question

Simplify 1 by 3 cube whole to the power 7

Answer 1

1/3 to the power of 21 is the answer

Answer 2

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 $\dfrac{1}{3^{21}}$
