Final answer:
To simplify the given expression 1.2 × 10^(-2) × 2.4 × 10^(-5), we multiply the base numbers and add the exponents. The simplified form is 2.88 × 10^(-7).
Step-by-step explanation:
To simplify the expression 1.2 × 10^(-2) × 2.4 × 10^(-5), we can use the rule of multiplying exponents. When multiplying numbers written in scientific notation, we multiply the base numbers and add the exponents.
1.2 × 2.4 = 2.88
10^(-2) × 10^(-5) = 10^(-2-5) = 10^(-7)
Therefore, the simplified form of the expression is 2.88 × 10^(-7).
