Answer:
64
Step-by-step explanation:
first, we'll start with the value inside the parenthesis, which is 2³
2³ means to multiply 2 by itself 3 times
so it would be
2×2×2=8
which then means that the expression is now (8)²
now we need to do (8)², which is to multiply 8 by itself twice
8*8=64

P+q= 5x^2+2
q-p= -(x-2) (x+2)
Answer:

Hope this helps :)
Note: a radioactive decay constant is always negative.
time = [natural log(ending amount / beginning amount)] / k
time = ln (20 / 24) / -.00011
time = ln (5/6) / -.00011
time = -.018232155683 / -.00011
