In all these expressions you have a power of a power.
You can solve them simply multiplying the exponents.
Remember that any quantity raised to the zero is equal to 1.

11) (n^4)^8 = n^(4×8) = n^32
13) (q^10)^10 = q^(10×10) = q^100
15) (x^3)^-5 = x^[3×(-5)] = x^(-15)
17) (z^8)^0z^5 = z^(8×0) z^5 = z^0 z^5 = 1×z^5 = z^5

Work Shown:
f(x) = x^2 - 3x
f(x) = ( x )^2 - 3*( x )
f(-18) = ( -18 )^2 - 3*( -18 ) ... replace every x with -18; now use PEMDAS
f(-18) = 324 - 3*( -18 )
f(-18) = 324 + 54
f(-18) = 378
Number 9 is yes, they are congruent.
number 10 is no, they are not congruent because x=3, so segment xy=3(3)+5 which is 14 and segment yz=9(3)/2 which is 13.5
Answer:
70% = 
20% = 
Step-by-step explanation:
We know that x% is represented by the fraction 
.
Now, in the first part, we are given two percentages 75% and 70%.
Now, 75% = 
and 70% =
Therefore, the second option is correct.
Again, in the second part, we are given two percentages 20% and 25%.
Now, 20% =
and 25% = 
Therefore, the third option is correct. (Answer)
Answer:
7
Step-by-step explanation:
What times 3 = 21 . 7 x 3 = 21 therefore 7 is the x
