Question

5⁷⁹+5⁷⁹+5⁷⁹+5⁷⁹+5⁷⁹=5^x
find the value of x​

Answer 1

Answer:

The answer is 80

Step-by-step explanation:

Given  $5^{79}+5^{79}+5^{79}+5^{79}+5^{79}=5^x$

          $\Rightarrow 5( 5^{79})=5^x$, since $5^{79}$ id added 5 times

          $\Rightarrow 5^{80}=5^x$

         $\Rightarrow 80=x$, equating exponents as bases are same

Hence the value of x is 80
