Well, isn't that just a lovely repeating decimal? Let's turn that into a fraction, shall we? If we call x = 0.5555555555, we can multiply x by 10 to get 10x = 5.5555555555. Then, we can subtract x from 10x to get 9x = 5, which simplifies to x = 5/9. And there you have it, a beautiful fraction created from that repeating decimal.
1/5 x x/35 = 7, 7 as a fraction is 7/1
To simplify the expression 5^4, you would calculate 5^4 as 5 x 5 x 5 x 5, which equals 625. As a fraction, 5^4 can be expressed as 625/1, since any number raised to the power of 0 is equal to 1.
