4.29 × 106 = 4290000
4.9 × 106 = 4900000
4.2 × 107 = 42000000
4.99 × 108 = 499000000
4200000 = 4200000
4.09 × 107 = 40900000
420000000 = 420000000
4.92 × 108 = 492000000
4090000 = 4090000
49000000 = 49000000

Standard form, also known as scientific notation, is a way of conveniently writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.
3.48 x 104
= 3.48 x 10 x 10 x 10 x 10
= 3.48 x 10000
= 34800
3.48 x 10-2
3.48 x 1⁄100
= 3.48 ÷ 100
= 0.0348
Finally note that any number raised to the power zero is 1 so:
3.48 x 100
= 3.48 x 1
= 3.48
