Question

Write these numbers in standard notation. 3.05 x 10–3 8.92 x 106

(The subject is science)

Answer 1

`3.05 * {10}^( - 3) =0.00305 \\8.92 * {10}^(6) = 8920000`

Answer 2

We have been given the two numbers:

`3.05 \cdot 10^(-3)`

And
`8.92\cdot 10^(6)`

`x^(-a)=(1)/(x^a)`

`10^(-3)=(1)/(10^3)=(1)/(1000)`

So,
`3.05 \cdot 10^(-3)=(3.05)/(1000)`

`\Rightarrow 0.00305`

And
`8.92\cdot 10^(6)=(892)/(100)\cdot {1000000}`

`892\cdot 10000`

`\Rightarrow 8920000`

`3.05 \cdot 10^(-3)=0.00305`

`8.92\cdot 10^(6)=8920000`
