We conclude that:
Step-by-step explanation:
Given:
[tex]-\left(9x\right)^0[/tex]
To determine:
Explain how to solve the expression
Solving the expression
[tex]-\left(9x\right)^0[/tex]
Apply the exponent rule
[tex]a^0=1,\:\quad \:a\ne \:0[/tex]
so the expression becomes
[tex]-\left(9x\right)^0\:=\:-1[/tex]
Therefore, we conclude that:
