Attempt following question by selecting a choice to answer. B
Solve for x. 4.1^{2x}  7 = 111ccc BBBA. B1.69 B. B2.68 C. B3.3 D. B0.59 BB
A
Step 1: 4.1^{2x}  7 = 111
Step 2: 4.1^{2x} = 111 + 7
Step 3: 4.1^{2x} = 118
Step 4: log 4.1^{2x} = log 118[Take the common log of each side.]
Step 5: 2 x log 4.1 = log 118[Use log N^{r} = r log N.]
Step 6: x = log 1182 log 4.1 [Divide throughout by 2 log 4.1.]
Step 7: x = 1.690546750[Use calculator.]
Step 8: x ≈ 1.69
