Question

-9 to the negative 1 power

Answer 1

Bear in mind that, (-9) and -9 are very different mammals, we're assuming, you meant (-9)⁻¹.



`\bf \left.\qquad \qquad \right.\textit{negative exponents}\\\\ a^{-{ n}} \implies \cfrac{1}{a^( n)} \qquad \qquad \cfrac{1}{a^( n)}\implies a^{-{ n}} \qquad \qquad a^{{{ n}}}\implies \cfrac{1}{a^{-{{ n}}}} \\\\ -------------------------------\\\\ (-9)^(-1)\implies \cfrac{1}{-9}\implies -\cfrac{1}{9}`
