Answer 2

ANS]

⭕

$\frac{6.7 \times {10}^{ - 11} \times 6 \times {10}^{24} \times 2 \times {10}^{30} }{ ({1.5 \times {10}^{11} )}^{2} }$

$\frac{6.7 \times {10}^{43} \times 6 \times 2 }{( {1.5 \times {10}^{11}) }^{2} }$

$\frac{6.7 \times 12 \times {10}^{43} }{22.5 \times {10}^{22} }$

$\frac{6.7 \times 12 \times {10}^{43 - 22} }{22.5 }$

$3.5733 \times {10}^{21}$
