Scientific Notation 2:

To perform the multiplication in scientific notation, we perform the multiplication of the two numbers, maintaining base 10 and adding the exponents.

Unlike addition and subtraction, we don’t need to have the same exponent to perform multiplication.

### Therefore, it will be given by the following formula:

a ⋅ 10m ⋅ b ⋅ 10n = (a ⋅ b) ⋅ 10m+n

### Being:

• a:  a number greater than or equal to 1 and less than 10;
• b:  a number greater than or equal to 1 and less than 10;
• m:  exponent given by an integer;
• n:  exponent given by an integer;

### Examples:

• (1,1 x 104) x (2,1 x 103)= → (1,1 x 2,1) x (104 x 103)= → 2,31 x 104+3 → 2,31 x 107
• 2 x 105 x 4 x 107 = (2 x 4) x 105+7 = 8 x 1012
