Please help me...
How do I express the following products in scientific notation??
1)(2.964 x 10^8) divided by (52 x 10^2)
2)(24.5 x 10 ^ negative 8) divided by (3x10^2)
3)(8.1 x 10^ negative 9) x (4 x 10^2)?

1.
2.964*10^8 /(52*10^2)
=2.964/52 *10^(82)
=0.057*10^{6}
=5.7*10^4
2.
(24.5 x 10 ^ negative 8) divided by (3x10^2)
=24.5/3 * 10^(8+2)
=8.1667*10^(6)
3. will leave to you as practice
