Solve for B in the equation: A = 5A^4B

a = -0.8b

Step-by-step explanation:

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4b' to each side of the equation.

5a + 4b + -4b = 0 + -4b

Combine like terms: 4b + -4b = 0

5a + 0 = 0 + -4b

5a = 0 + -4b

Remove the zero:

5a = -4b

Divide each side by '5'.

a = -0.8b

Simplifying

a = -0.8b

step-by-step explanation:

taking away equals subtraction. 6-4=2

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
