Question

Evaluating Logarithms In Exercise, evaluate the logarithm without using a calculator. log10 1

Answer 1

Answer:

0

Step-by-step explanation:

To evaluate log10 1 without using a calculator

From the laws of logarithm,

Logₐ b = x

Then a^x = b

Therefore if log10 1 = x

10^x = 1

From the laws of indices (any figure raised to the power of 0 = 1)

a^0 = 1

Therefore, x = 0

log10 1 = 0

Answer 2

Answer:

x=64

Step-by-step explanation:

b.

log^4  x=3

Convert to exponential form and simplify.

4^3 = x

x=64

Therefore, log^4 64=3
