5^2=3^18+ 2^8

To solve this equation, we can start by simplifying the exponents on both sides.

On the left side, we have 5^2, which is equal to 25.

On the right side, we have 3^18 + 2^8.

To simplify 3^18, we can use the property that (a^m)^n = a^(m*n). So, we have:

3^18 = (3^2)^9 = 9^9.

To simplify 2^8, we can calculate it directly, which is equal to 256.

Now, our equation becomes:

25 = 9^9 + 256.

To solve for 9^9, we can calculate it directly, which is equal to 387,420,489.

Now, our equation becomes:

25 = 387,420,489 + 256.

However, this equation is not true. Therefore, there is no solution to the equation 5^2 = 3^18 + 2^8.
