To determine

To calculate: The simplified form of expression xy1x1

Explanation

Given Information:

The provided expression is xy1x1.

Formula used:

For any real number a other than 0.

aman=a(m+n)

Where a is base and m, n are real exponents.

Zero exponent

a0=1

Where a is any real number other than 0

Calculation:

Consider the provided expression xy1x1.

Rearrange the expression as,

xy1x1=xx1y1

Now simplify further by the use of exponent identity aman=a
