Solve the following:$(7^2)^3 \times [(\frac{1}{7})^2]^3$
Given :
The given expression is $(7^2)^3 \times [(\frac{1}{7})^2]^3$.
To do :
We have to solve the given expression.
Solution :
We know that,
$a^m \times a^n = a^{m+n}, (a^m)^n = a^{m\times n}$ and $a^{-m} = \frac{1}{a^m}$
$(7^2)^3 \times [(\frac{1}{7})^2]^3 = (7)^{2 \times 3} \times (\frac{1}{7})^{2\times 3}$
$= 7^6 \times (\frac{1}{7})^6$
$= 7^6 \times 7^{-6}$
$= (7)^{6+(-6)}$
$= (7)^{6-6}$
$ = 7^0$
$= 1$. (Any number raised to the power of 0 is 1)
Therefore, the value of $(7^2)^3 \times [(\frac{1}{7})^2]^3$ is 1.
