Question

An Angstrom is a very small unit of measure. So is a micron. One metre
equals 1010 Angstroms. One metre also equals 1000 000 microns. Use an
exponent rule to determine how many Angstroms are in one micron.

Answer 1

10^10 angstroms**

Answer 2

1 m = 10^10 angstroms

1 m = 1 000 000 = 10^6 microns

1 m = 1 m

10^10 angstroms = 10^6 microns

Divide both dided by 10^10

1 angstrom = 10^6 / 10^10 micron

1 angstrom = 10^ ( 6 - 10 ) micron

1 angstrom = 10^ ( - 4 ) micron

1 angstrom = 0.0001 micron

Answer 3

You mean 1 meter = 10^10 Angstroms
and 1 meter = 10^6 microns
so 10^10 Angsroms = 10^6 microns
so
1 micron * ( 10^10 Ang / 10^6 micron) = 10^4 Angstroms

Answer 4

Or

10^10 angstroms = 10^6 microns

Divide both dided by 10^6

10^4 angstrom = 1 micron

1 micron = 10^4 angstrom

1 micron = 10 000 angstrom
