Step-by-step explanation:

If you break down each part into 5 to the power of something, you get the following:

When you simplify this, you get:

, which simplifies to 1

Step-by-step explanation:

The first factor is (5^6)^3.  Multiply the exponents 6 and 3 together, obtaining 5^18.  Next, rewrite 25^3 as (5^2)^3, or 5^6.  Finally, write 125^8 as (5^3)^8.  

Then we have:

5^18 * 5^6           5^24

= = 1

(5^3)^8               5^24

* 25^3

125^8

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
