Let x=3.48×53.82067. Then x2=3.48×53.82067. Taking the logarithm of both sides (base 10), we have:
2log10(x)=log10(2067)−log10(3.48)−log10(53.8) log10(x)=21[log10(2067)−log10(3.48)−log10(53.8)] We need to approximate the logarithms using a logarithm table. Since we don't have access to a physical table, we will use a calculator instead.
log10(2067)≈3.3153 log10(3.48)≈0.5416 log10(53.8)≈1.7308 Substituting these values into the equation:
log10(x)=21[3.3153−0.5416−1.7308] log10(x)=21[3.3153−2.2724] log10(x)=21[1.0429] log10(x)=0.52145 Now, we need to find the antilogarithm of 0.52145, which is 100.52145. x=100.52145≈3.322
