Log6(6^9)=???

Question

Answer: 9

Ine^-3x=???

Answer: -3x

Use log5(2) = 0.4307 and log5(3) = 0.6826 to approximate the value of log5(12)

Answer:

log5(2) + log5(3)=log5(2^2*3)
2(0.4307) + 0.6826=1.544
so approximate value of log5(12)=1.544

I appreciate your checking my work.

Answer 1

Log6(6^9)=???
9 log6(6) = 9*1
Answer: 9 Right

Ine^-3x=???

Answer: -3x Right

Use log5(2) = 0.4307 and log5(3) = 0.6826 to approximate the value of log5(12)

Answer:

log5(***4***) + log5(3)=log5(2^2*3)

2(0.4307) + 0.6826=1.544

Right method,, did not check arithmetic

so approximate value of log5(12)=1.544
