Prove that (81/16)^-3/4 ×[(25/9)^-3/2 ÷ (5/2)^-3]=1

andreev551 [17]

Answer:

First write them in positive exponent form

(16/81)¾ × [ (9/25)^3/2 ÷ (2/5)³ ]

(2⁴×¾)/ (3⁴×¾) × [ (3² × ^3/2) / (5² ×^3/2) ÷ 2³/5³)

Simplify the terms

2³/3³ × ( 3³ / 5³ ÷ 2³/5³)

Solve the terms in the bracket

2³/3³ × (3³/5³×5³/2³)

You will get

2³/3³ × 3³/2³ = 1

They will cancel each other so the answer will be 1

Hope this helps.

baherus [9]

Answer:

$Each =\pounds 1121$

Step-by-step explanation:

See comment for complete question.

Given

$Total = \pounds 8968$

$Projects = 8$

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

$Each =\frac{Total}{Projects}$

$Each =\frac{\pounds 8968}{8}$

$Each =\pounds 1121$

<em>Each project gets £1121</em>

Look at the attached file. <br><br> please show your work on how you got the answer

statuscvo [17]

Answer:

Step-by-step explanation:

$\frac{f(x)}{g(x)}$

= $\frac{2x+4}{2x^2+4x}$

Factor out 2 on the numerator and 2x on the denominator.

= $\frac{2(x+2)}{2x(x+2)}$

Cancel the factor (x + 2) on the numerator/ denominator

= $\frac{2}{2x}$ ← cancel the 2 on numerator/ denominator

= $\frac{1}{x}$ : x ≠ 0
