Answer 1

2)

a) the number is: 0.000000045 so in scientific notation will be:

`0.000000045=4.5*10^(-8)`

b) the number is 246:

`246=2.46*10^2`

c) the number is 0.000234

`0.000234=2.34*10^(-4)`

d) the number is 698.4

`698.4=6.984*10^2`

e) the number is 0.469

`0.469=4.60*10^1`

f) the number is 0.00000000000000000002 so:

`0.00000000000000000002=2.0*10^(-20)`

3)

a) The number is 1.53x10^-3

`1.53*10^(-3)=0.00153`

b) the number is 8.54x10^4 so:

`8.54*10^4=85400`

c) the number is 6.04x10^6 so:

`6.04*10^6=6040000`

d) the number is 4.234x10^-5 so:

`4.234*10^(-5)=0.00004234`

e) the number is 4.0x10^2

`4.0*10^2=400`

f) the number is 3.4567x^6

`3.4567*10^6=345670`
