Calculate: x ^ 3 y ^ 0 x ^ 5 x ^-7

Expression: $$x ^ { 3 } y ^ { 0 } x ^ { 5 } x ^ { - 7 }$$

To multiply powers of the same base, add their exponents. Add $3$ and $5$ to get $8$.

$$x^{8}y^{0}x^{-7}$$

To multiply powers of the same base, add their exponents. Add $8$ and $-7$ to get $1$.

$$x^{1}y^{0}$$

Calculate $x$ to the power of $1$ and get $x$.

$$xy^{0}$$

Calculate $y$ to the power of $0$ and get $1$.

$$x\times 1$$

For any term $t$, $t\times 1=t$ and $1t=t$.

$$x$$
