(5^3 * 2^-6)^-2 = 2^w/c^x

we can first reciprocate both sides, note that z^-b = 1/z^b where z is real and cannot equal zero and b is real. So reciprocating just turns it into z^b, in this case, imagine z = (5^3 * 2^-6) and b = 2.
Note that reciprocal also means ‘to the power of -1’ and using exponent rules means (z^-b)^-1 = z^(-1*b*-1) = z^b

Therefore,

[(5^3 * 2^-6)^-2]^-1 = [2^w/c^x]^-1

z^b = c^x/2^w

(5^3 * 2^-6)^2 = c^x/2^w

using exponent rules, including reciprocation,

5^6*2^-12 = c^x/2^w

and again,

5^6/2^12 = c^x/2^w

now 5 and 2 are relatively prime (do not have any common factors); in fact, they are both distinct prime numbers, so they would not share any factors. This also means that the numerator is in its ‘prime factorised’ form, as well as the denominator. I am assuming we are looking for integer solutions.

Therefore, the solutions naturally come out.

c = 5

x = 6

w = 12

Answer:

4. H

5. I

6. L

Step-by-step explanation:

The constant 2 has disappeared on the bottom line. That happens when 2 is subtracted from it. -2 has been subtracted from both sides of the equation using the subtraction property of equality. (H)

The left-side constant -1 has disappeared on the bottom line. That happens when 1 is added to it. 1 has been added to both sides of the equation using the addition property of equality. (I)

Parentheses have moved from enclosing the last two factors on the left side to enclosing the first two factors. The associative property of multiplication allows parentheses to be moved wherever you like among the factors of a product. (L)

Given the isosceles right triangle in which each of its legs has a measure of 4:

Let c = hypotenuse
a = one of the legs of the triangle
b = the other leg of the triangle

Use the Pythagorean Theorem to solve for the measure of the hypotenuse:

c^ 2 = a^2 + b^2

c^ 2 = (4)^2 + (4)^2
c^ 2 = 16 + 16
c^2 = 32

Next, take the square root of each side of the equation to solve for c:

√(c^2) = √(32)

c = 4√(2)

Therefore, the correct answer is Option 3) 4√(2).

WHATS THE ANSWER TO THIS??

Answers

Answer:

y - 1.4x = - 6.8

Step-by-step explanation:

To find the equation: find the slope, use point-slope form to calculate the equation, then convert the equation to standard form.

Slope: [tex]\frac{45-31}{37-27} = \frac{14}{10} = 1.4[/tex]

Use point slope form: y - y₁ = m(x - x₁)

Plug in x = 27, y = 31, and m = 1.4

y - 31 = 1.4(x - 27)

y - 31 = 1.4x - 37.8

y = 1.4x - 6.8

Convert this into standard form: ax + by = c

y - 1.4x = - 6.8

Ok done. Thank to me :>

Answer:

132 cm²

Step-by-step explanation:

The area of the two triangular ends is ...

A = 2(1/2)(bh) = (4 cm)(3 cm) = 12 cm² . . . . . area of both triangles

The area of the three rectangular faces is ...

A = (b1)(h) +(b2)(h) +(b3)(h) = (b1 +b2 +b3)(h)

= (4 cm +3 cm +5 cm)(10 cm) = 120 cm²

Then the total surface area is ...

triangle area + rectangle area = (12 cm²) +(120 cm²) = 132 cm²

Answers

The value of x and y is 2 and 11.5

The sum of the interior angle of a triangle is 180 degrees.

Since LMN and PQR are similar, hence:

m<L = m<P

m<M = m<Q

m<N = m<R

Given the following parameters

m< L = 40 degrees

m<M = 90 degrees

m<P = 17x - y

m<R = 2x + 4y

Get the measure of m<N

m<M + m<N + m<L = 180

90n+ m<N + 40 = 180

m<N = 180 - 130

m<N = 50degrees

Since m<P = m<L, hence;

17x - y = 40 ....... 1

Also m<R = m<N

2x + 4y = 50 .......... 2

Solve simultaneously

17x - y = 40 ....... 1 * 4

2x + 4y = 50 .......... 2 * 1

___________________________

68x - 4y = 160

2x + 4y = 50

Adding both equations

68x + 2x = 160 + 50

70x = 210

x = 2

Substitute x = 3 into the equation 2x + 4y = 50

2(2) + 4y = 50

4 + 4y = 50

4y = 50 - 4

4y = 46

y = 46/4

y = 11.5

Hence the value of x and y is 2 and 11.5
