When log 5 + log 4 is rewritten log n, what is the value of n?

log 10³ - log 40

• log 1000

• log 960

• log 25

• 25

• log 0.25

log₅ 25 = x. Find x

log₄ x =1.5

2 log 2 + log 25

Find the value of x when e^{ln x} = 4

Solve the equation 3^x = 12 to 3 s.f

 $\frac{1}{2}\log_5\left(1\frac{9}{16}\right)+2\log_510$  

Express $\frac{1}{2}\log_qx^{15}$   in the form  $p\log_qx$  

•  $\frac{15}{2}\log_qx$  

•  $\frac{1}{30}\log_q15$  

•  $\frac{1}{2}\log_{15}q$  

•  $\log_qx^{30}$
