Which is the simplified form of (9c^-9)^-3 b 1/729 c^27

rosijanka [135]

ANSWER

$(9 {c}^{ - 9} )^{ - 3}=\frac{{c}^{ 27} }{729}$

EXPLANATION

The given expression is

$(9 {c}^{ - 9} )^{ - 3}$

Recall that:

$({a}^{m} )^{n} = {a}^{mn}$

We use the law of exponents to get

$(9 {c}^{ - 9} )^{ - 3} = 9^{ - 3} {c}^{ - 9 \times - 3}$

Let us multiply in the exponents to get:

$(9 {c}^{ - 9} )^{ - 3} = 9^{ - 3} {c}^{ 27}$

Recall again that:

${a}^{ - m} = \frac{1}{ {a}^{m} }$

This implies that:

$(9 {c}^{ - 9} )^{ - 3} = \frac{1}{ {9}^{ 3} } \times {c}^{ 27}$

We expand the power to get:

$(9 {c}^{ - 9} )^{ - 3} = \frac{1}{9 \times 9 \times 9} \times {c}^{ 27}$

$(9 {c}^{ - 9} )^{ - 3}=\frac{1}{729} \times {c}^{ 27}$

We multiply out to get:

$(9 {c}^{ - 9} )^{ - 3}=\frac{{c}^{ 27} }{729}$

If you guys can figure this out ur a genius

Answer:

252 ft squared

Step-by-step explanation:

Since the radius of the circle is 3, then the diameter would be 6

Split the rectangle into 3

The way I split the shape is like the picture attached (with the blue lines).

Find the area of each rectangle which can be easily found by using the diameter of each circle (picture attached with black lines)

6*18=108

6*12=72

Add the areas of each rectangle.

108+72+72=252

The first painter can finish a paint job in 2 hours. The second painter can finish the same job in 8 hours. How long would it ta

vampirchik [111]

Answer: $1\frac{3}{5}$ hrs

Step-by-step explanation:

1st painter: $\frac{1}{2}$

2nd painter: $\frac{1}{8}$

1st + 2nd = Together

$\frac{1}{2}$ + $\frac{1}{8}$ = $\frac{1}{x}$

$\frac{1}{2}(8x)$ + $\frac{1}{8}(8x)$ = $\frac{1}{x}(8x)$

4x + x = 8

5x = 8

x = $\frac{8}{5}$

= $1\frac{3}{5}$
