Simplify the expression [tex]$x^5 \cdot x^7$[/tex].


Sagot :

To simplify the expression [tex]\( x^5 \cdot x^7 \)[/tex], we need to apply the properties of exponents. Specifically, there's a rule that tells us how to handle the multiplication of powers with the same base.

When you multiply two expressions with the same base, you add the exponents. In general,

[tex]\[ a^m \cdot a^n = a^{m+n} \][/tex]

In this case, our base is [tex]\( x \)[/tex], and our exponents are [tex]\( 5 \)[/tex] and [tex]\( 7 \)[/tex]. Therefore, we add the exponents:

[tex]\[ x^5 \cdot x^7 = x^{5+7} \][/tex]

Now, compute the sum of the exponents:

[tex]\[ 5 + 7 = 12 \][/tex]

Thus, the simplified form of the expression is:

[tex]\[ x^{12} \][/tex]

So, the correct answer is:

[tex]\[ x^{12} \][/tex]
