1. Express 4 factors of -20: (-20%)(-2)(-20)(-28)
2. Expand the expression:
-2.-2.-2.-2..0.0.
3. Simplify to the exponential form: (-2)4. (4574
4. Evaluate the base 2 power: 16. (054
5. Apply the power of a power: 162"
What is the value of x in the simplified power? x=

The value of x in the simplified power is 20.

Solution:

Given expression:

Step 1: Express 4 factors of

Step 2: Expand the expression

Step 3: Simplify to the exponential form

There four -2 terms and four terms.

Step 4: Evaluate the base 2 power.

Step 5: Apply the power of a power.

Using exponent rule:

So that

⇒ x = 20

The value of x in the simplified power is 20.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
