Answer:
a) 2.477121
b) 10
c) 1000
Step-by-step explanation:
a) Your calculator can tell you ...
log(3) ≈ 0.477121
so ...
2+log(3) ≈ 2.477121
__
b) The relation between logs and anti-logs is ...
log(x) = y ⇔ y = 10^x
"a logarithm is an exponent"
So, ...
log(x) = 1 ⇒ x = 10^1 = 10
c) log(x) = 3 ⇒ x = 10^3 = 1000
?
-17 =s
-8s +4 = -7s +21
Add 8s to each side
-8s+8s +4 = -7s+8s +21
4 = s+21
Subtract 21 from each side
4-21 = s+21-21
x>4
Sorry if there is any mistakes
