Final answer:
To write an expression using four 8's that equals 8, we can divide 8 by 8 four times or use negative exponents.
Step-by-step explanation:
To write an expression using four 8's that equals 8, we can use properties of operations and exponents.
One way to do this is by using division. We can divide 8 by 8 four times, which can be represented as 8 ÷ 8 ÷ 8 ÷ 8 = 1.
Another way is by using negative exponents. We can write 8 as 8⁰, and then use negative exponents to divide 8⁰ by 8 three times, which can be represented as 8⁰ ÷ 8¯³ = 1.
So, using properties of operations and exponents, we can write the expression 8 ÷ 8 ÷ 8 ÷ 8 or 8⁰ ÷ 8¯³ to equal 1.
