a. ????=1
b.????=2
c. ????=4
d.(x-1)²(x+1)=0
(x²-1)(x-1)=0
x³-x²-x+1=0
x³-x²-x+2=1
Answer:
Step-by-step explanation:
This can be simplified into
which is saying that you are taking the cubed root of each of those bases. The cubed root of 8 comes out evenly, to 2 (since 2*2*2 = 8). The cubed root of 320 is not so simple. To find it, find the complete factorization of 320. 320 factors to: 5 * 2*2*2*2*2*2 or
Split that 2^6 up into increments of 3's to make the simplifying a bit easier:
Because the index (the little number sitting in the bend of the radial sign) matches the power on both the 2's we can pull both the 2's out front, leaving:
but don't forget that we already found that the cubed root of 8 was 2, so multiply that 2 by the 4 to get:
