Question

Use the properties of exponents to simplify the expression: [tex]25^{\frac{3}{2}}[/tex]

Answer:

[tex]25^{\frac{3}{2}} = 125[/tex]\

Step-by-step explanation:

Given

[tex]25^{\frac{3}{2}}[/tex]

Required

Simplify

[tex]25^{\frac{3}{2}}[/tex]

Apply the following law of indices

[tex]a^{\frac{m}{n}} = (a^m)^{\frac{1}{n}}[/tex]

So, the expression becomes

[tex]25^{\frac{3}{2}} = (25^3)^{\frac{1}{2}}[/tex]

Express [tex]25^3[/tex] as 15625

[tex]25^{\frac{3}{2}} = (15625)^{\frac{1}{2}}[/tex]

In indices: [tex]a^{\frac{1}{2}} = \sqrt a[/tex]

So, we have:

[tex]25^{\frac{3}{2}} = \sqrt{15625[/tex]

[tex]25^{\frac{3}{2}} = 125[/tex]
