Factor completely 50a2b5 – 35a4b3 + 5a3b4
answer
10b2 – 7a2 + ab
a2b3(50b2 – 35a2 + 5ab)
5(10a2b5 – 7a4b3 + a3b4)
5a2b3(10b2 – 7a2 + ab)

The factored form of the given expression is

Step-by-step explanation:

We have been given the expression

In order to factor it completely we can check for the GCF (greatest common factor) among all the three terms

The GCF is

On factor out the GCF, we are left with

Therefore, the factored form of the given expression is

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
