$(1.5 \cdot 10^{- 7}) \cdot (3.6 \cdot 10^{15}) \div (1.2 \cdot 10^{- 3})$

Step 1

Convert the fraction to a decimal by dividing the numerator by the denominator.

$450000000000$

Step 2

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the $10$ . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

$4.5 \times 10^{11}$
