Question

Is this the right answer.

questions: use properties of logarithms to solve each equation
10^1-2x = 72

my answer 1.43

Answer 1

log 10 - 2x log 10 = log 72

is that what you did?

Answer 2

nope

Answer 3

Property of logarithms:\[\log_{b}a=c <=>a=b^c \]
This means that you can rewrite an equation like yours in an exponential form and vice versa:\[10^{1-2x}=72 <=>\log_{10}72=1-2x \]Now you can go on solving x...
