hope it helps uh!!!!

anshii35: see I edit the ans.
anshii35: there is also ruf work
ProKing417: the ans is wrong
ProKing417: it is 2.01 x 10^20
anshii35: yaa it can also be
anshii35: just wait
ProKing417: so urs is Wrong
anshii35: wait
anshii35: only there is a mistake in decimals
anshii35: u can correct it by urself

Answer:

\text {F = } 2.02 \times 10^{20} \text { (3 significant figure)}


Step by Step Explanation:

Algebraic Identify needed:

aⁿ x aˣ = aⁿ⁺ˣ

aⁿ/aˣ = aⁿ⁻ˣˣ

(aⁿ)ˣ = aⁿˣ


Scientific Form:

A x 10ⁿ where A is between 1 to less than 10


Question:

\text {F = } \dfrac{6.7 \times 10^{-11} \times 6 \times 10^{24} \times 7.4 \times 10^ {22} }{(3.84 \times 10^8)^2}


Apply aⁿ x aˣ = aⁿ⁺ˣ and (aⁿ)ˣ = aⁿˣ

\text {F = } \dfrac{(6.7 \times 6 \times 7.4)(10^{-11+24+22}) }{14.7456 \times 10^{16}}

\text {F = } \dfrac{297.48 \times 10^{35} }{14.7456 \times 10^{16}}


Apply aⁿ/aˣ = aⁿ⁻ˣˣ

\text {F = } 20.174 \times 10^{35 - 16}


Write in A x 10ⁿ

\text {F = } 20.174 \times 10^{19}


Answer:

\text {F = } 2.02 \times 10^{20} \text { (3 significant figure)}


ProKing417: there's no 20.2 in ans
TooFree: the answer is 2.02 .. that is why we increase 10^19 to 10^20
TooFree: Both 20.2 x 10^19 = 2.02 x 10^20 [They are just in different form. The second one in scientific form]
ProKing417: Ohh 20.174.Rounded off to 20.2
ProKing417: and 20.2 become 2.02
TooFree: yes
ProKing417: ohhh
ProKing417: A should be Less than 10
ProKing417: that's why you put 2.02
TooFree: yes
