Answer:
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
(a^b)^c = a^(bc)

Your expression simplifies as follows:
Answer:
multiply the midpoint by 2
Step-by-step explanation:
On a number line, the midpoint is the exact middle of all the included values. Since it is the middle it would numerically be half of the endpoint. Therefore, the best and easiest way to find the endpoint would be to multiply the midpoint by 2. This is essentially doubling the midpoint value to get the endpoint. For example, lets say the midpoint is 3 then we can multiply it by 2 to get the endpoint which would be 6
Answer:
Step-by-step explanation:
We want use the order of operations and the digits 2, 4, 6, and 8 to create an expression with a value 2.
The expression is:
The order of operations is PEDMAS
Deal with parenthesis first,
Next deal with exponent
No Division and Multiplication so skip to Addition.
Finally subtract to get:
Answer:
d 13
Step-by-step explanation:
Subtracting means adding the opposite.
To subtract -4, you add the opposite of -4 which is 4, so you add 4.
9 - (-4) = 9 + 4 = 13
Answer: d 13
Answer:
-10
Step-by-step explanation:
We can figure out that the number line is by four.
How?
There is one line between 10 and 2. Sooo:
10 - 2 = 8
8 / 2 = 4
If we check it (10 - 4 - 4 = 2) it checks out!
Using this information we can figure out what the blue dot is.
2 (given) - 4 (incriments of number line) - 4 - 4 = - 10
There is our answer, -10!
