Question

$(4 \times {10}^{2} )(6 \times {10}^{ - 5}) \div 8 \times {10}^{10}$
​

Answer 1

Answer:

3 * 10⁻¹³

Step-by-step explanation:

(4 * 10²)(6 * 10⁻⁵) ÷ 8 * 10¹⁰

= (4 * 6 * 10² * 10⁻⁵ )  ÷ 8 * 10¹⁰

= (24 * 10² * 10⁻⁵ )  ÷ 8 * 10¹⁰

= (24 * 10²⁻⁵  )  ÷ 8 * 10¹⁰

= (24 * 10⁻³  )  ÷ 8 * 10¹⁰

= (24 ÷ 8) * (10⁻³ ÷  10¹⁰)

= 3 * 10⁻³⁻¹⁰

= 3 * 10⁻¹³
