Question

2 simplify the expression using exponents. $(-2) \times (-2) \times (-2) \times (-2)$ \
a $(-2)^4$ \
b $2^4$ \
c $8^4$ \
d $-8^4$

Explanation:

Step1: Recall exponent definition

An exponent \(a^n\) means \(a\) multiplied by itself \(n\) times, where \(a\) is the base and \(n\) is the exponent.

Step2: Identify base and exponent

In the expression \((-2)\times(-2)\times(-2)\times(-2)\), the base is \(-2\) and it is multiplied 4 times. So, using the exponent notation, this is \((-2)^4\).

Answer:

A. \((-2)^4\)
