Question

It would be amazing if u helped me with the question below, thx! <3

Answer 1

namely, how many times does 4 x 10⁻³ go into 8 x 10⁶.

`\bf ~~~~~~~~~~~~\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)}\\\\-------------------------------\\\\\cfrac{\stackrel{elephant}{8* 10^6}}{\stackrel{ant}{4* 10^(-3)}}\implies \cfrac{8}{4}* \cfrac{10^6}{10^(-3)}\implies 2* 10^6\cdot 10^3\\\\\\2* 10^(6+3)\implies 2.0* 10^9`
