Part b: simplify the expression -6-4. is the
result the same as simplifying the expression
(-6)-4. explain.
pls fast

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

i found two solutions,   n = 2 • ± √3 = ± 3.4641
