Hello from MrBillDoesMath!
Answer: 2 ^ -4 ( = 1/16)
Discussion:
- 4 log {8} 2 {8} is used instead of subscript notation
Basic property of logarithms is that exponents become multipliers and vice versa:
-4 log {8} 2 = log {8} (2^ -4)
Thank you,
MrB
To work out the LCM, we need their prime factors. So:
2 is simple 2 x 1.
7 is also 7 x 1.
13 is also 13 and 1.
They all have in common "1" - so we keep that aside as 1 figure, rather than 3.
We still have the 2, 7 and 13 leftover.
We then multiply the 1 with the other figures.
So 1 x 2 x 7 x 13 is our answer.
Which is = 182.
Hope I helped:)

First find the factors of 20
1 & 20
2 & 10
4 & 5
-1 & -20
-2 & -10
-4 & -5
Now find the pairs that have a difference of 1
-4 & -5
4 & 5
The graph of a quadratic equation is a U-shaped curved called parabola. It is because the parabola makes very easy to find the axis of symmetry to plot selected points and finding the roots and vertex.
Good luck :)
Answer:
x=7
Step-by-step explanation:
y=mx
5.5=m×11
5.5÷11=m
m=1/2
y=mx
3.5=1/2×x
3.5÷1/2=x
x=7
