When you multiply two negatives (-, -,), you are gonna get a positive(+)
<em>[Like making a cross out of two lines].</em>

<h2>Since 3(7) normally <u>
equals 21</u>, that would be the answer for this case.</h2>
If 4=2^2
8=2^3
(2^)2x+10=(2^)6x
(2^)6x-(2^)2x=10
(2^)2x×7=10, where x has no real value
Scientific notation is used to express very large or very small values.
Numbers in scientific notation are written in the form of
m × 10 to the power of n
For example:
500 is written as 5 x 10^2 where:
500 = 5 x 10 x 10
Now, let's consider 7 x 10^3:
Following the same procedure:
7 x 10^3 = 7 x 10 x 10 x 10 = 7000
The pattern can be written as:
7 x 10^3 = 7 x 10 x 10^2
= 70 x 10^2
= 70 x 10 x 10^1
= 700 x 10
= 7000
Answer: 32 students
Step-by-step explanation: 8 x 4 = 32
N = 4.
I’m not sure if that was what you were asking though.
