+529 Determine x such that 10x = 2.278768 x 1042
So, taking logx of both sides, we have
x·log10(10) = log10(2.278768) + 42•log10(10)
x = 0.3577001 + 42
= 42.3577001 (Answer)
It's difficult to check this on a calculator, so to verify the approach repeat it but using an example you can realistically evaluate on a calculator, e.g.,
Determine x such that 10x = 2.278768 x 104
and if after you determine the value of x you check that the right side equals the left here, you may conclude that your answer in the first part should be right, too.
