Question

With 1 ≤ |a| < 10 and N is an integer.

Answer 1

So a times 10^n where 1≤|a|<10 and n is an integer is what i learned


so

a.
234=
2.34 times 100=
2.34 times 10²


b.
0.000052=
5.2 times 1/100000=
5.2 times 10⁻⁵



c.
-220000=
-2.2 times 100000=
-2.2 times 10⁵


d.  ok, so just count the spaces moved to the left
-18.2 times 10⁻¹⁵
