Rewrite in Scientific Notation:

524 x 10100

= 5.24 x 102 x 10100

= 5.24 x 10102

Have your homework out on your desk.

RE- Try this CHALLENGE question:

Simplify and write the answer in scientific notation.

(3.9 x 10652) + (7.3 x 10650)

= (390 + 7.3) x 10650

= (397.3) x 10650

= (3.973 x 102) x 10650 = 3.973 x 10652

= [(3.9 x 102) + (7.3)] x 10650
