Question

Rewrite using a negative exponent

1/(xy)^1

1/a^4

1/8^6

5/x^2

Answer 1

1/(xy)^1 = x^-1y^-1

1/a^4 = a^-4

1/8^6 = 8^-6

5/x^2 = 5x^-2

Answer 2

Answer: The expressions are written below.

Step-by-step explanation: We are given to write the given expressions using negative exponents.

We will be using the following property of exponents :

`(1)/(p^h)=p^(-h).`

The first expression is :

`E_1=(1)/((xy)^1)=(xy)^(-1).`

The second expression is :

`E_2=(1)/(a^4)=a^(-4).`

The third expression is :

`E_3=(1)/(8^6)=(1)/(2^(3*6))=(1)/(2^(18))=2^(-18).`

The fourth expression is :

`E_4=(5)/(x^2)=5x^(-2).`
