3 and 1/4 should be your answer.

the first thing you want to do is convert the 1/2 beside the 12 to 2/4ths so you can subtract the two fractions. your new equation would be 12 2/4 - 9 1/4. subtract 1/4th from 2/4ths and you'll get 1/4th. subtract 9 from 12 and you'll get 3.
your answer comes up as 3 and 1/4th.

Answer:

$2{x}^{ \frac{3}{2} }$

Step-by-step explanation:

We want to simplify:

$\frac{ {x}^{2} + {x}^{2} }{ {x}^{ \frac{1}{2} } }$

We first simplify the numerator to obtain:

$\frac{ 2{x}^{2} }{ {x}^{ \frac{1}{2} } }$

Next the quotient rule:

$\frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n}$

We apply this quotient rule to get:

$\frac{ 2{x}^{2} }{ {x}^{ \frac{1}{2} } } = 2{x}^{2 - \frac{1}{2} }$

Simplify exponents:

$\frac{ 2{x}^{2} }{ {x}^{ \frac{1}{2} } } = 2{x}^{ \frac{3}{2} }$

Therefore the given expresion simplifies to:

$2{x}^{ \frac{3}{2} }$
