Answer:


3 \cdot 10^(-10)

Explanation:


(1.2\cdot 10^(-3))/(4\cdot 10^(6))=(12\cdot 10^(-4))/(4\cdot 10^(6))\\\\=(12)/(4)\cdot 10^(-4-6)=3\cdot 10^(-10)

I like to adjust the operands so the quotient needs no adjustment. Here that means rewriting the numerator to an equivalent value with a mantissa between 4 and 40.
