Answer: 1. 3801
Step-by-step explanation:
Log 24 = Log(8x3)
From the laws of Logarithm
Log ( a xb) = Log a + Log b
so, Log (8x3) = Log8 + Log 3
Also Log 8 can be written as Log
since
is still 8 , so the expression becomes
Log
+ Log 3
⇒ 3 Log 2 + Log 3
since the value of Log 2 and Log 3 has been given , substitute into the expression , we have
3 (0.3010) + 0.4771
= 0.903 + 0.4771
= 1.3801
Answer:
x=-3
Step-by-step explanation:
-7-4(2x-1)=21
-7-8x+4=21
-7+4-8x=21
-3-8x=21
8x=-3-21
8x=-24
x=-24/8
x=-3
