Answer :

To solve the equation [tex]\((-20)^{16} \cdot (-20)^x = (-20)^2\)[/tex], we will use the properties of exponents.

Step-by-Step Solution:

1. Identify the property of exponents to use:

When multiplying exponential expressions with the same base, [tex]\(a^m \cdot a^n = a^{m+n}\)[/tex]. Here, the base is [tex]\(-20\)[/tex].

2. Rewrite the equation using the property:

[tex]\[ (-20)^{16} \cdot (-20)^x = (-20)^{16+x} \][/tex]

3. Equate the exponents:

Once we have the expressions on both sides with the same base, we can set the exponents equal to each other:

[tex]\[ 16 + x = 2 \][/tex]

4. Solve for [tex]\(x\)[/tex]:

Subtract 16 from both sides of the equation to isolate [tex]\(x\)[/tex]:

[tex]\[ x = 2 - 16 \][/tex]

Simplify the result:

[tex]\[ x = -14 \][/tex]

So, the value of [tex]\(x\)[/tex] is [tex]\(-14\)[/tex].
