Rewrite the expression in the form 5^n<br> 5^10/5^12
weqwewe [10]

Answer:

Step-by-step explanation:

This problem is all about bases and exponents.  Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

\frac{5^{10}}{5^{12}}=5^{10-12}=5^{-2}

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

PLEASE HELP!!!!!!! IMA DESPRATE!!!!!!! A radioactive isotope decays exponentially. The time it takes for half of the amount to d
ki77a [65]

Since the isotope is initially 154 mg, the amount of radioactive isotope left after 64 hours is 9.625 mg

To answer the question, we need to know what radioactive decay is.

<h3>What is radoactive decay?</h3>

Radioactive decay is the spontaneous disintegration of a larger atom to a smaller one

<h3>What is half-life?</h3>

Half-life of a radioactive isotope is the time it takes for the isotope to decay to half its initial value.

<h3>Amount left after n half lives</h3>

The amount left after n half lives is N = (1/2)ⁿN₀ where N₀ = initial mass of isotope.

Given that the half-life of the isotope is 16 hours, and we desire the amount present after 64 hours.

The number of half-lives after 64 hours is n = time/half-life

= 64 h/16 h

= 4

Since we have 154 mg of isotope present, N₀ = 154 mg

Given that

  • n = 4 and
  • N₀ = 154 mg

Substituting the values of the variables into N, we have

N = (1/2)ⁿN₀

N = (1/2)⁴ × 154 mg

N = 154 mg/16

N = 9.625 mg

So, the amount of radioactive isotope left after 64 hours is 9.625 mg
