Question

Write the logarithmic form of y=8^x

What is the logarithmic form of 7^3=343

What is the exponential form of log_416=2

 

What is the value of each logarithmic equation

a) log_3(1/81)  b) log_7(-7)  c) log_5 5^9

Answer 1

The way I remember it is that the first and last change places.

 

y = log_ax

x = a^y

 

y = 8^x

x = log₈y

 

log₄16 = 2

16 = 2^4y

 

The rest is on you!
