Question

simplify: $(-5x)^0 + (4x)^0 - 4x^0$
a -5
b -4
c -2
d 3

Explanation:

Step1: Apply zero exponent rule

Any non-zero term to the 0 power is 1. So $(-5x)^0 = 1$, $(4x)^0 = 1$, and $x^0 = 1$.

Step2: Substitute values into expression

$1 + 1 - 4\times1$

Step3: Calculate the result

$1+1-4 = 2-4 = -2$

Answer:

C. -2
