Question

UpStudy AI · Accepted Answer

Substitute $$ m=-1 $$ into the expression $$ m^{2}-m^{3}-m^{4} $$.
Evaluate the expression by following steps:
- step0: Evaluate:
  $$m^{2}-m^{3}-m^{4}$$
- step1: Substitute:
  $$\left(-1\right)^{2}-\left(-1\right)^{3}-\left(-1\right)^{4}$$
- step2: Evaluate the power:
  $$1-\left(-1\right)^{3}-\left(-1\right)^{4}$$
- step3: Evaluate the power:
  $$1-\left(-1\right)^{3}-1$$
- step4: Evaluate the power:
  $$1-\left(-1\right)-1$$
- step5: Subtract the terms:
  $$2-1$$
- step6: Subtract the numbers:
  $$1$$
When $$ m = -1 $$, the expression $$ m^{2}-m^{3}-m^{4} $$ evaluates to 1.
The expression evaluates to 1.
