Answer:
3
Step-by-step explanation:
we know that product do extreme is equal to the product of means
105:280::x:8
105*8=280x
840=280x
x=840/280
x=3
Log8 2 = x
by the definition of logs, we can write
8^x = 2
8^(1/3) = 2
so x = 1/3
or we could solve it by using log to base 10 and use our calculator
log 8^x = log 2
x log 8 = log 2
x = log 2 / log 8 = 0.333.... = 1/3
Answer:
-7
Step-by-step explanation:
f(x)=4x+5
Let x =-3
f(-3)=4*-3+5
Multiply
f(-3)=-12+5
Add
f(-3) = -7
