Logs & Exponentials Quiz

Does this graph represent exponential growth or decay?

• Growth
• Decay

Evaluate the log:
log₃(1/9) = 

• 1/2
• 2
• -2
• 3

Rewrite as a single log:
log 5 + log 7

• log 12
• log -2
• log 35
• undefined

Write as a single log:
log 12 - log 2

• log 6
• log 10
• 0
• 2

Rewrite using log rules:
log₄x²

• log₄ + logx²
• log4/logx²
• log₄x²
• 2log₄x

Rewrite logt = m in exponential form.

• e^t = m

• t^m = 10

• m^t = e

• 10^m = t

Rewrite 3⁴ = 81 in logarithmic form.

• log₃4 = 81
• log₈₁3 = 4
• log₃81 = 4
• log₄81 = 3

• none of these
  

• 5logm + logn

• logm - 5logn

• 5log(m - n)
