Can I get some help on this? it wants it solved for L

Lady bird [3.3K]

Multiply both sides by 2pi:

F(2pi) = sqrt(g/l)

Square both sides:

F^2 (2pi)^2 = g/l

Solve for l by dividing both sides by F^2 (2pi)^2

L = g/ F^2 (2pi)^2

Simplify:

L = g / 4pi^2(f^2)

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".
