Factorising expressions in algebra is a fundamental concept that helps simplify complex expressions into more manageable forms. In this article, we will explore the factorisation of a specific expression: x1/xy1/y. This process involves breaking down the expression into simpler components and understanding the underlying mathematical principles.
Factorising the Expression
Let us start with the given expression: x1/xy1/y. The goal is to simplify this expression step-by-step. Here’s a detailed breakdown:
Initial Expression: x1/xy1/y
Step 1: Group the terms in the exponent.
x1/xy1/y xxy1/y1/x1/y
Step 2: Simplify the exponent. Notice that 1/xy1/y xy1/x can be rewritten based on the properties of exponents.
xxy1/x1/y1/y xxy1/x1/y
Step 3: Combine the exponents by grouping the terms.
xxy1/x1/y xxy1/xxy1/y1/x
Step 4: Simplify the expression by evaluating the fraction inside the logarithmic term:
x1/x1/y x1/xy
Step 5: Continue simplifying the fraction. Notice that the terms can be further simplified:
x1/x1/y x1/xy
After following these steps, we can see that the expression x1/xy1/y simplifies to:
x1/x1/y x1/xy
