2^2x+2 *5^x-1=8^x*5^2x
Liula [17]

Answer:

The solution will be "x = 2 and x = -1".

Step-by-step explanation:

The given equation is:

⇒  2^{2x+2}\times 5^{x-1}=8^x\times 5^{2x}

On solving "8^x", we get

⇒  2^{2x+2}\times 5^{x-1}=(2^3)^x\times 5^{2x}

As we know, if the base are same then their powers will be added together.

⇒  2x+2=3x ...(equation 1)

⇒  x-1=2x ...(equation 2)

From equation 1, we get

⇒  2=3x-2x

⇒  2=x \ i.e., x =2

From equation 2, we get

⇒  -1=2x-x

⇒  -1=x \ i.e., x=-1

So that the correct answer will be "x = 2" and "x = -1".
