Solve for a x^(3/2)x^(5/4)=x^a

$x^{\frac{3}{2}} x^{\frac{5}{4}} = x^{a}$

Rewrite the equation as $x^{a} = x^{\frac{3}{2}} x^{\frac{5}{4}}$ .

$x^{a} = x^{\frac{3}{2}} x^{\frac{5}{4}}$

Multiply $x^{\frac{3}{2}}$ by $x^{\frac{5}{4}}$ by adding the exponents.

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$x^{a} = x^{\frac{3}{2} + \frac{5}{4}}$

To write $\frac{3}{2}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$x^{a} = x^{\frac{3}{2} \cdot \frac{2}{2} + \frac{5}{4}}$

Write each expression with a common denominator of $4$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{3}{2}$ by $\frac{2}{2}$ .

$x^{a} = x^{\frac{3 \cdot 2}{2 \cdot 2} + \frac{5}{4}}$

Multiply $2$ by $2$ .

$x^{a} = x^{\frac{3 \cdot 2}{4} + \frac{5}{4}}$

Combine the numerators over the common denominator.

$x^{a} = x^{\frac{3 \cdot 2 + 5}{4}}$

Simplify the numerator.

Multiply $3$ by $2$ .

$x^{a} = x^{\frac{6 + 5}{4}}$

Add $6$ and $5$ .

$x^{a} = x^{\frac{11}{4}}$

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

$a = \frac{11}{4}$

The result can be shown in multiple forms.

Exact Form:

$a = \frac{11}{4}$

Decimal Form:

$a = 2.75$

Mixed Number Form:

$a = 2 \frac{3}{4}$
