Question

Write 1.9 x 10 to the power of negative 4 in standard form

Answer 1

Answer: 0.00019

Step-by-step explanation: To write
`1.9`
`x`
`10^(-4)` in standard notation, we first look at the exponent on the power of 10 which in this case is -4. A negative exponent means that we move the decimal point to the left.

So in this case, we move the decimal point in 1.9 four places to the left and fill in the missing positions with zeroes to get .00019 or 0.00019.

So
`1.9`
`x`
`10^(-4)` can be written as 0.00019.
