Answer:
[tex]R=-3.64603\times 10^{23}[/tex]
Explanation:
It is required to simplify R. We have,
[tex]R=(1149\times 10^9\ m)^2-(1298\times 10^9\ m)^2[/tex]
It can be calculated step by step such that,
[tex](1149)^2=1320201\\\\\text{and}\\\\(1298)^2=1684804[/tex]
Plugging these values,
[tex]R=[(1149)^2\times (10^9)^2]-[(1298)^2\times (10^9)^2)]\\\\R=1320201\times 10^{18}-1684804\times 10^{18}\\\\R=-3.64603\times 10^{23}[/tex]
