Will give brainliest, <br> (404/4)x(2x2) to the power of 2.

Ganezh [65]

Answer:

163216

Step-by-step explanation:

If it's the sign of multiplication

404/4=101

2*2=4*101=404^2=163216

or,

If it's x

(404/4)x(2x2)

(101)x(2x2)

101x (4x)^2

1616x^2

2611456

I am not sure if it's right

(2/3 - 3/4 × 1/8) ÷ (2/3 - 3/4 + 5/8)

kati45 [8]

<h3>Given:</h3>

$( \frac{2}{3} - \frac{3}{4} \times \frac{1}{8} ) \div ( \frac{2}{3} - \frac{3}{4} + \frac{5}{8} )$

<h3>Solution:</h3>

First, solve the brackets.

First bracket:

$( \frac{2}{3} - \frac{3}{4} \times \frac{1}{8} )$

$= \frac{55}{96}$

Second bracket:

$( \frac{2}{3} - \frac{3}{4} + \frac{5}{8} )$

$= \frac{13}{24}$

Then divide.

$\frac{55}{96} \div \frac{13}{24}$

$= \frac{55}{52} \: or \: 1\frac{3}{52}$

Solve for x:<br> 17 - 4x = 33

MrRissso [65]

Answer:

solve for X

17-4x=33

-4x=33-17

-4x=16

-4x/-4=16/-4

x=-4

Step-by-step explanation:

1. move the constant (17) to the right side

2. subtract the numbers on the right side (33-17)

3. Divide both sides of the equation by -4 (/4)

4. write the answer x= -4

Solved.
