Simplify the expression. Assume that all variables represent nonzero real numbers.StartFraction (4 n Superscript 4 Baseline q Su

Alja [10]

Answer:

$\frac{ - 3}{ 256 {q}^{10} {n}^{8} }$

Step by step explanation:

$\frac{ {(4 {n}^{4} {q}^{5})}^{2} {(8 {n}^{4} q)}^{-2} }{ {(- 3 {nq}^{9})}^{ - 1} {(4 {n}^{3} {q}^{9}) }^{3} }$

first we will change the terms with negative superscrips to the other side of the fraction

$\frac{{(4 {n}^{4} {q}^{5})}^{2}{(- 3 {nq}^{9})}^{ 1}}{{(4 {n}^{3} {q}^{9})}^{3} {(8 {n}^{4} q)}^{2} }$

then we will distribute the superscripts

$\frac{ {4}^{2} {n}^{2 \times 4} {q}^{2 \times 5} (- 3) {nq}^{9}}{ {4 }^{3}{n}^{3 \times 3} {q}^{9 \times 3} {8 }^{2}{n}^{4 \times 2} {q}^{2} }$

$\frac{ {4}^{2} {n}^{8} {q}^{10} (- 3) {nq}^{9}}{ {4 }^{3}{n}^{9} {q}^{27} {8 }^{2}{n}^{8} {q}^{2} }$

as when multiplying two powers that have the same base, we can add the exponents and, to divide podes with the same base, we can subtract the exponents

${4}^{2 - 3} {q}^{10 + 9 - 2 - 27} {n}^{8 + 1 - 8 - 9} {8}^{ - 2} { (- 3)}^{1}$

${4}^{ - 1} {q}^{ - 10} {n}^{ - 8} {8}^{ - 2} { (- 3)}^{1}$

then we will change again the terms with negative superscrips to the other side of the fraction

$\frac{ - 3}{ 4 \times {8}^{2} {q}^{10} {n}^{8} }$

$\frac{ - 3}{ 256 {q}^{10} {n}^{8} }$

If are is 24cm² find the x

Nimfa-mama [501]

Answer:

$x = 6$

Explanation:

Given:

$Area = 24cm^2$

See attachment for shape

Required

Find x

The attached shape is a rectangle.

So:

$x * 4 = 24$

$4x = 24$

Divide both sides by 4

$\frac{4x}{4} = \frac{24}{4}$

$x = \frac{24}{4}$

$x = 6$

The volume of a pyramid with a square base is given by the expression suh, where s is the length of a side of the base and h is

Maslowich

Answer:

Step-by-step explanation:

The volume of a pyramid with a square base is given by the expression suh,

where

s is the length of a side of the base.

h is the height.

From the information given,

The side length,s of the square base = 24 feet.

The height, h other pyramid = 30 feet.

Area of the square base = s^2 = 24^2 = 576

Volume = area × height × 1/3

Volume = 576 × 30 × 1/3

Volume = 5760 ft^3

MRS, JOHNSON JUST PURCHASED A TOTAL OF 12 BOOKS AND MAGAZINES FOR HER OFFICE. THE TOTAL BILL WAS $112. SHE SPENT $16 ON MAGAZINE

Anuta_ua [19.1K]

To do this problem, we can right an equation assuming the number of booked she bought is x:

16 + 12x = 112

First we will isolate the variable by subtracting 16 from both sides:

12x = 96

Then we will divide each side by 12:

x = 8

Since the number of books she bought is x, that must mean that:

Mrs. Johnson bought 8 books.
