What is the expression for f(x) when we rewrite <br> (5⁻⁴ˣ⁺⁷)÷(125x) as 5^f(x)
alexandr402 [8]

Answer: The answer is f(x) = -7x + 7.


Step-by-step explanation:  We are give a relation as follows :

5^{-4x+7}\div 125^x=5^{f(x)}.

From here, we need to find the expression for f(x).

Here, we will be using the following properties of exponents :

(i)~\dfrac{a^x}{a^y}=a^{x-y}.\\\\(ii)~a^x=a^y~\Rightarrow x=y.

We have

5^{-4x+7}\div 125^x=5^{f(x)}\\\\\Rightarrow5^{-4x+7}\div 5^{3x}=5^{f(x)}\\\\\\\Rightarrow \dfrac{5^{-4x+7}}{5^{3x}}=5^{f(x)}\\\\\\\Rightarrow 5^{-4x+7-3x}=5^{f(x)}}\\\\\Rightarrow 5^{-7x+7}=5^{f(x)}\\\\\Rightarrow -7x+7=f(x).

Thus, the required expression is f(x) = -7x + 7.

A = bh
A = (22)(18)
A = 396 m²

A = ¹/₂h(b₁ + b₂)
A = ¹/₂(8)(16 + 12)
A = ¹/₂(8)(28)
A = ¹/₂(224)
A = 112 cm²

   P = 2l + 2w
 20 = 2l + 2(4)
 20 = 2l + 8
- 8         - 8
 12 = 2l
  2      2
   6 = l

C = 2πr
C = 2(3.14)(8)
C = 2(25.12)
C = 50.24 in

A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 m²
