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:
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
