Question

(9.2×10^5)(4×10^-3)​

Answer 1

first change the 9.2 to standard form. which is

`92 * {10}^( - 1)`

now the whole equation becomes

`(92 * {10}^( - 1) * {10}^( - 5) ) * (4 * {10}^( - 3) )`

`= 92 * 4 * {10}^( - 1 + 5 - 3)`

`= 368 * {10}^(1)`

`= 3.68 * {10}^(2 + 1)`

`= 3.68 * {10}^(3)`
