Question

What is the best estimate for this equation can you show me step by step

Answer 1

Given the expression below

`(23.8*10^7)/(4.2*10^2)`

To estimate the expression, we apply the exponent rule

`\begin{gathered} =(23.8)/(4.2)*(10^7)/(10^2) \\ =5.66667*10^(7-2) \\ =5.66667*10^5 \\ =5.67*10^5\text{ \lparen best estimate\rparen} \end{gathered}`

Hence, the best estimate is 5.67 x 10⁷
