Question

A.) 2 logbq + 8 logbt
B.) 4 log x – 6 log (x + 2)

Answer 1

1) log_b(q^2t^8)

2)none of these

3) log_5(7)+5log_5(a)

4)6.209

5)81 decibels

Answer 2

a)
`2log_(b)q + 8 log_(b) t= \\ log_(b) q^(2) + log_(b) t^(8) = \\ log_(b) q^(2) t^(8)`
Answer: B )
b )
`4 log x - 6 log( x + 2 ) = log x^(4) - log ( x+2 )^(6)= \\ log ( x^(4) )/((x+2) ^(6) )`
Answer: D ) None of those
