Question

How do you convert 1550 into scientific notation?

Answer 1

`1550 = 1.55 xx 10^3`
`color(white)("XXXX")` `color(white)("XXXX")`(into scientific notation)

Explanation:

Scientific notation represents numbers as
`color(white)("XXXX")`a mantissa multiplied by `10` to an exponent
`color(white)("XXXX")` `color(white)("XXXX")`where the "mantissa" is a single non-zero digit followed by a decimal point and a sequence of remaining digits, and
`color(white)("XXXX")` `color(white)("XXXX")`the exponent indicates the number of decimal digit locations the decimal point needs to be moved to the right to represent the intended value.

The mantissa for `1550` is `1.550`

The exponent, the number of places to the right we need to move the decimal point of `1.55` to the right in order to make it equivalent to `1550` is 3.
