x^{x + 2} + x^{4} \cdot x^{2 x + 3}

$x^{x + 2} + x^{4} \cdot x^{2 x + 3}$

Step 1

Use the power rule

a^{m} a^{n} = a^{m + n}

$a^{m} a^{n} = a^{m + n}$ to combine exponents.

x^{x + 2} + x^{4 + 2 x + 3}

$x^{x + 2} + x^{4 + 2 x + 3}$

Step 2

Add

4

$4$ and

3

$3$ .

x^{x + 2} + x^{2 x + 7}

$x^{x + 2} + x^{2 x + 7}$
