Help! Pls! I'm lost. I would really appreciate it if anyone knows all the answers. (Math; Scientific Notations)

1) b. 1.562x10⁸

2) a. 4.8x10⁶

4) d. 2.3x10³

5) a. 4.21x10 -⁶

6) 6.6835x10⁵

Step-by-step explanation:

1) (2.2x10⁴)•(7.1x10³)= 156200000

2) 9.6x10⁹÷2x10³= 4800000

4) 6.9x10⁸= 2300

5) 5.6x10 -⁷ + 3.65x10 -⁶= 4.21x10 -⁶

6) 6.72x10⁵ - 3.65x10³= 668350

entering that problem on the tube might get you an answer

part a
