Answer 2

$\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}=7$

Step-by-step explanation:

Given : Expression $\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}$

To find : Simplify the expression ?

Solution :

Expression $\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}$

Using algebraic identity,

$a^b\times a^c=a^{b+c}\\\\\frac{a^b}{a^c}=a^{b-c}$

$\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}=\frac{7^{8+3+4}}{7^{9+5}}$

$\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}=\frac{7^{15}}{7^{14}}$

$\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}=7^{15-14}$

$\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}=7^{1}$

$\frac{7^8\times 7^3\times 7^4}{7^9\times 7^5}=7$
