Remember that when the exponents look like this (5^2)^-3, you multiply the exponents together
when it looks like this:
5^3 x 5^2 you add the exponents
so my example would equal 5^5
also remember that you can’t have negative exponents
To solve your problem:
1. multiply the exponents here: (5^2)^-3
2. add the exponents in the next step when you multiply by the 5^4
3. now, you should get a negative exponent on the top, and you already have one on the bottom. to get rid of these negative exponents, move the one in the denominator to the numerator and vice versa
so when you move the 5^-4 in the denominator to the numerator, it becomes 5^4
4. now, you simplify. you can either subtract the exponents and do it that way, or you can solve the exponents and then divide. either way will work, although the first is easier
Answer:
Its Either B or C
Step-by-step explanation:
It does have 180 degree angles
It has point symmetry
The way the angles are labeled tell you that they are all congruent. The two triangles you see here also share the side that joins them. Then by the angle-side-angle postulate, the two triangles are congruent, so x + 23 = 13, or x = -10.
50 x 20 = 1000, 20 + 36 = 56 so 56 hours
Answer:
No, it is not
Step-by-step explanation:
Here, we want to check if what we have is a function
For a relation to be a function, the mapping must be one to one or many to one
This mean, for every x there must be one y or for every y, there must can be multiple x
But never is it that there are many y for a single x
Looking at the value 0
on the domain, we can see -2 and 1 as the values
Thus, this is not a function
