What is the prime factorization of 1,260A. 2x2x3x3x5x7b. 2x3x5x7c. 4x5x7x9d. 2x3x5x6x7

Answers

Answer 1

Answer: to find out the prime factorization of 1260 you need to "decompose" this number in prime numbers
first step i will divide the 1260 by numbers that I know it is divisible by (ends in 0 so it will be 10, sum of the digits is 9 so will be divisible by 3)
1260=126*10=9*14*10=3*3*2*7*2*5
i need to write the prime numbers in order
1260=2*2*3*3*5*7 is choice A

Answer 2

Answer:

Answer:

Let’s count every 4 as 2^2, and put the negative in front of the parentheses. The result would be -(2^2*2^2*2^2*2^2*2^1*2^2*2^2*2^2*2^2*2^2*2^2*2^2*2^1), or -2^(2+2+2+2+1+2+2+2+2+2+2+2+1), or -2^12, which would be -4096.

Answer:

$(1)/(2^7)$

Step-by-step explanation:

To express the number 2⁻⁷ with a positive exponent, we'll make use of the properties of exponents and their relationship with reciprocals.

$\hrulefill$

Here's a list of the exponent properties:

$\boxed{\left\begin{array}{ccc}\text{\underline{Properties of Exponents:}}\n\n1.\ a^0=1\n\n2.\ a^m * a^n=a^(m+n)\n\n3.\ a^m / a^n \ ((a^m)/(a^n) )=a^(m-n)\n\n4.\ (ab)^m=a^mb^m\n\n5.\ (a/b)^m=a^m/b^m\n\n6.\ (a^m)^n=a^(mn)\n\n7.\ a^(-m)=1/a^m\n\n8.\ a^(m/n)=(\sqrt[n]{a} )^m\end{array}\right}$

In our case, we will use the reciprocal identity (#7 on the table above).

$a^(-m)=(1)/(a^m) \n\n\n\n\therefore 2^(-7)=\boxed{(1)/(2^7) }$

Thus, we can represent 2⁻⁷ as a positive exponent .

The solutions for the given problems we have:

1) The solution of the inequality is:

x ≤ 2

2) The absolute value equation has two solutions:

z= 2

z = -12

3) The correct matches are:

5y + 2 = 5y + 8 this has no solutions

2*(y + 4) = 2y + 8 this has infinite solutions

5y + 2 = 2y + 8 This has a single solution.

Here, we have,

Remember that solving means to isolate the variable in one side of the expression.

1) We have the inequality:

-4x + 17 ≥ 9

-4x ≥ 9 - 17

x ≤ -8/-4

x ≤ 2

This is the solution of the inequality.

2) We have the absolute value function:

|5 + z| + 3 = 10

|5 + z| = 10 - 3 = 7

We can decompose this into:

5 + z = 7

5 + z = -7

Then the two solutions are:

z = 7 - 5 = 2

z = -7 - 5 = -12

3) The correct matches here are:

5y + 2 = 5y + 8 this has no solutions, these are parallel lines.

2*(y + 4) = 2y + 8 this has infinite solutions (all real numbers).

5y + 2 = 2y + 8 This has a single solution.

p(p - q) - q(q - p). Multiply out.

p*p - p*q - q*q + q*p.

Note because of the minus before the bracket, the minus inside the bracket changes to +

p² - pq -q² + pq

p² - q² + pq - pq

p² - q² + 0

p² - q²

Answers

-5y - 9 = -(y - 1)

First, simplify your brackets. / Your problem should look like: $-5y - 9 = -y + 1$
Second, regroup the terms. / Your problem should look like: $-5y - 9 = 1 - y$
Third, add 5y to both sides. / Your problem should look like: $-9 = 1 - y + 5y$
Fourth, simplify 1 - y + 5y to 1 + 4y. / Your problem should look like: $-9 = 1 + 4y$
Fifth, subtract 1 from both sides. / Your problem should look like: $-9 - 1 = 4y$
Sixth, subtract -9 - 1 to get -10. / Your problem should look like: $-10 = 4y$
Seventh, divide both sides by 4. / Your problem should look like: $-(10)/(4) = y$
Eighth, simplify $(10)/(4)$ to $(5)/(2)$ / Your problem should look like: $- (5)/(2) = y$
Ninth, switch your sides. / Your problem should look like: $y = -(5)/(2)$
