Math III - 2nd Six Weeks Review (3rd) 11/9

Simplify the exponential expression.

• 2x⁶y¹²
• 2x⁵y⁷
• 8x⁶y¹²
• 8x⁵y⁷

2^x+6=32

• x=-1
• x=11
• x=1
• x=-11

Write the expression as a single logarithm.   Then simplify if possible.
log₅3 + log₅6 + log₅9

• log₅69
• log₅56
• log₅162
• log₅98

• -.5609
• 3.4036
• 2.0674
• -1.0753

• (2e+2)/3
• 0
• (2e-2)/3
• (3e-2)/2

Evaluate.
log₆(¹/₂₁₆)

• 3
• ¹/₃
• -¹/₃
• -3

Write in exponential form.
log₂32 = 5

• 2^-5 = 32
• 2³² = 5
• 2⁵ = 32
• 32⁵ = 2

Write  5² = 25  in logarithmic  form

• log₅   2 = 25
• log₅    25  =  2
• log₂  25  = 5
