What is equivalent to 5 to the 2nd power times 5 to the 2nd power

adelina 88 [10]

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>

<h2>Explanation:</h2>

In this case, we have the following statement:

<em>5 to the 2nd power times 5 to the 2nd power. </em>In a mathematical language:

$5^2\times 5^2$

From product rules, we know that:

$a^n \cdot a^m=a^{n+m}$

Applying this rule to our problem:

$5^2\times 5^2=5^{2+2}=5^4=625$

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>
