Answer 2

Answer:

please give me thanks.

Step-by-step explanation:

Consider the given equation is

\dfrac{2^{5x}}{2^x}=\sqrt[5]{32}

2

x

2

5x

=

5

32

We need to find the value of x.

It can be rewritten as

\dfrac{2^{5x}}{2^x}=\sqrt[5]{2^5}

2

x

2

5x

=

5

2

5

Using the properties of exponents we get

2^{5x-x}=22

5x−x

=2 [\because \dfrac{a^m}{a^n}=a^{m-n}, \sqrt[n]{a^n}=a][∵

a

n

a

m

=a

m−n

,

n

a

n

=a]

2^{4x}=2^12

4x

=2

1

On comparing both sides we get

4x=14x=1

x=\dfrac{1}{4}x=

4

1

Therefore, the value of x is 1/4.
