Simplify this solution Extra Insights
To simplify \( (7.10^{8}).(3.10^{5}) \), first, multiply the coefficients 7 and 3 to get 21. Then, add the exponents of the powers of 10: \( 8 + 5 = 13 \). So, you’d have \( 21.10^{13} \). However, to express it in proper scientific notation, since 21 is greater than 10, we rewrite it as \( 2.1 \times 10^1 \) and combine that with \( 10^{13} \), resulting in \( 2.1 \times 10^{14} \).
