Question

solve it ................

Answer 1

[6.67*(10^-11)*8*12*(10^3)]/(10^2)

= [667*8*12*(10^-2)*(10^-11)]/{10^2}

= [667*96]/{10^(13)*(10^2)}

= 64032/{10^15}

= 64032*10^(-15)

= 64.032*10^(-12)

Answer 2

Answer:

$6.4032 \times 10^{-8}$

Step-by-step explanation:

$\dfrac{6.67 \times 10^{-11} \times 80 \times 1200}{10^2}$

$= \dfrac{6.67 \times 10^{-11} \times 8 \times 10 \times 1.2 \times 10^3}{10^2}$

$= 6.67 \times 10^{-11} \times 8 \times 10 \times 1.2 \times 10^3 \times 10^{-2}$

$= 6.67 \times 8 \times 1.2 \times 10^{-11 + 1 + 3 - 2}$

$= 64.032 \times 10^{-9}$

$= 6.4032 \times 10^{-8}$
