Question

about how much energy did russia, india, and japan consume in 2010? what is \\((3 \times 10^{19}) + (2 \times 10^{19}) + (2 \times 10^{19})\\)? primary energy consumption for top 5 countries in 2010. country | energy consumed in 2010 (joules) china | \\(1.06 \times 10^{20}\\) u.s. | \\(1.03 \times 10^{20}\\) russia | \\(3.09 \times 10^{19}\\) india | \\(2.31 \times 10^{19}\\) japan | \\(2.30 \times 10^{19}\\) \\((3 \times 10^{19}) + (2 \times 10^{19}) + (2 \times 10^{19}) = ? \times 10^{?}\\) joules

Explanation:

Step1: Factor out \(10^{19}\)

We have the expression \((3\times 10^{19})+(2\times 10^{19})+(2\times 10^{19})\). Using the distributive property \(ab + ac+ad=a(b + c + d)\), where \(a = 10^{19}\), \(b = 3\), \(c = 2\), and \(d=2\), we can factor out \(10^{19}\):
\((3 + 2+2)\times10^{19}\)

Step2: Add the coefficients

Calculate the sum of the coefficients: \(3+2 + 2=7\)

Step3: Write the result

So the expression simplifies to \(7\times 10^{19}\)

Answer:

The first? is \(7\) and the second? is \(19\), so the result is \(7\times 10^{19}\)
