I know it is a little messy but the answers are
For the first one = (0,7.5)
Second one = (0, 5 2/3)
To estimate this, round 53 to 50 and 12 to 10. 50 times 10 will be roughly what? 500. that is the estimated answer. the real answer is 636.
Step-by-step explanation:
step 1. 1 3/4 - p > 1/2
step 2. 7/4 - p > 2/4. get common denominators
step 3. -p > -5/4. subtract 7/4 from both sides
step 4. p < 5/4 divide by -1. remember to switch the arrow when you divide by a negative number
step 5. so the answer is anything less than 5/4 which means 9/8, 7/8, 1/4.
Every non-zero complex number has three cube roots. In general, any non-integer exponent, like
1
3
here, gives rise to multiple values. The way we find them is by multiplying
z
by 1 before exponentiating. We write
1
using Euler's Identity to the

k
power for integer

. That's
