Find the value of the expression 8 x (3^3 + 2) - 11 Level 1-2 dok 1

232x

Step-by-step explanation: (8x)(33+2)

=(8x)(33)+(8x)(2)

=216x+16x

=232x

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
