Rewrite the logarithm in exponential form: lnb = 2

Rewrite the logarithm in exponential form: ln42 = x

• lnm = -5

• ln(-5) = m

• ln48 = n

• ln(n) = 48

Solve the equation. Round your answer to four decimal places: ln(8 - 10k) = -2

• k = 0.7865

• k = -0.7369

• k = 1.0193

• k 1.3383

Solve the equation. Round your answer to four decimal places: ln(2k + 4) = -2

• k = -1.9323

• k = 0.0778

• k = 3.8647

• k = 1.0898

• x = 0.9365

• No solution

• x = 0.5736

• x = 0.6492

• n = -1.6112

• n = -2.1140

• n = -2.0759

• n = -2.1260
