Simplify the following:
$3^2 \times 3^4 \times 3^8$
$(5^2)^3 \div 5^3$
Given :
The given expressions are $3^2 \times 3^4 \times 3^8$ and $(5^2)^3 \div 5^3$.
To do :
We have to simplify the given expressions.
Solution :
$3^2 \times 3^4 \times 3^8$
We know that,
$a^m \times a^n = a^{m+n}$
$3^2 \times 3^4 \times 3^8 = 3^{2+4+8} = 3^14$
Therefore, the simplified form of $3^2 \times 3^4 \times 3^8$ is $3^14$.
$(5^2)^3 \div 5^3$
We know that,
$(a^m)^n = a^{m \times n}, a^m \div a^n = a{m-n}$
$(5^2)^3 \div 5^3 = 5^{2\times 3} \div 5^3 = 5^6 \div 5^3 = 5^{6-3} = 5^3$
Therefore, the simplified form of $(5^2)^3 \div 5^3$ is $5^3$.
