I need help please.
makkiz [27]

Answer:

see explanation

Step-by-step explanation:

Using the rules of radicals/ exponents

a^{m} × a^{n} = a^{(m+n)}

a^{\frac{m}{n} } ⇔ \sqrt[n]{a^{m} }

Simplifying each term

7\sqrt{x^{3} } = 7x^{\frac{3}{2} }

x\sqrt{9x}

= x × \sqrt{9} × \sqrt{x}

= x × 3 × x^{\frac{1}{2} }

= 3 × x^{(1+\frac{1}{2}) }

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

Subtracting the 2 simplified like terms, that is

7x^{\frac{3}{2} } - 3x^{\frac{3}{2} }

= 4x^{\frac{3}{2} } ← return to radical form

= 4\sqrt{x^{3} }
