Given:

Consider the given expression is

[tex]5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}[/tex]

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}[/tex]

Using properties of exponents, we get

[tex]=5^{-\frac{5}{2}+\frac{9}{2}}[/tex]           [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]=5^{\frac{-5+9}{2}}[/tex]

[tex]=5^{\frac{4}{2}}[/tex]

[tex]=5^{2}[/tex]

[tex]=25[/tex]

Therefore, the simplified form of given expression is 25.
