Answer:

$n=3$

Step-by-step explanation:

Note that $2^5*5^2=2^3*2^2*5^2=2^3*(2*5)^2=2^3*10^2$ .

Aha! We see a path to the solution!

We now know that our equation is actually $2^3*10^2=2^{n}*10^2$ .

We can divide both sides by $10^2$ to get $2^3=2^{n}$ .

By inspection or taking the logarithm base 2 of both sides, we see that $3=n$ .

So, the answer is $\boxed{n=3}$ and we're done!

Which of the following properties can be used to show that the expression 4^{\frac{5}{3}} is equivalent to \sqrt[3]{4^{5}}

pantera1 [17]

Answer:

see below

Step-by-step explanation:

Not knowing what properties you have to choose from, it'll be one that looks like $a^{\frac{m}{n}}=\sqrt[n]{a^{m}}$ ;

The base (a) stays the same;

the Numerator in the exponent is the exponent on the base;

and the Denominator in the exponent is the index (root number) of the radical.
