Which number is written correctly in scientific notation? 1) 0.459×10^8
2) 25.6×10^12
3) 3,892× 10^7
4) 5.03×10^11​

1)4.59 *10^7

2)2.56 *10 ^13

3)3.892 *10 ^10

4)5.03 *10 ^11

You would multiply by the numerator/denominator on both sides. This is because a fraction is basically division and the opposite of division is multiplication.

For example, say you had 2=x/4

To solve this equation, you would multiply by 4 on both sides.

So, x=8 (because you canceled the 4 out and 4x2=8).

I hope this helped!
