Sagot :
Answer:
[tex]-\frac{1}{5}[/tex]
Step-by-step explanation:
⇒ [tex]5^{-1}[/tex] is the same as [tex]\frac{1}{5}[/tex]
⇒ [tex]-9^{0}[/tex] is the same as 1
*Note that it is not one as you must follow BIDMAS rules - you do 9 to the power of 0 before multiplying by the negative (which is -1)
⇒ 1/5 ÷ - 1
⇒ 1/5 × 1/ - 1
⇒ 1/-5
