Answer:
28
Step-by-step explanation:
784 can be divided by two 4 times.
This means that there are two pairs of 2s that can come out the radical.
2*2 = 4.
then now we have 49 left inside and we know that this is 7 squared, meaning that there is a pair of 7 inside the radical.
7 comes out and now we have 7 times 4 which is 28.
Answer:
x³+y³=4697
Step-by-step explanation:
x+y=11
y=11-x
325=x²+y²
=x²+(11-x)(11-x)
=x²+121-11x-11x+x²
325=2x²-22x+121
0=2x²-22x-204
=(2x+12)(x-17)
0=2x+12 or 0=x-17
-12=2x 17=x
-6=x
y=11-x
y=17 or -6
(-6,17) or (17,-6)
=x³+y³
=(-6)³+(17)³
=4697
