Answer:
D.
Step-by-step explanation:
There are six (-2), so it would be D. since C. would just mean and turn that negative.
You can check using a calculator that (-2)(-2)(-2)(-2)(-2)(-2) would equal 64 while C. equals -64. So the correct answer would be D.
Literal equation:
we know that
literal equation is equation of more one variable
for example:
And we can solve such equations only if we are given two such equation
because it has two variables
One variable equation:
such equation has single variables
for example:
we don't need any other equation
we can solve for variables from single equation itself
because it has only one variable that is x
