When you add two integers, does the order matter? Why?

1 answer:

6 0

As long as you keep the signs with the numbers the order doesn't matter. The cumulative property says that you can flip the numbers in any order and it will equal the same amount.

The rules of exponents tell you to add exponents in the numerator and subtract those in the denominator. A power of a power causes the exponent to be multiplied.

$\dfrac{(2x^{3}z^{2})^{3}}{x^{3}y^{4}z^2x^{-4}z^{3}}=2^{3}x^{(3\cdot3-3-(-4))}y^{-4}z^{(2\cdot3-2-3)}\\\\=\dfrac{8x^{10}z}{y^{4}}$

Step-by-step explanation:

$given \\ (x + \frac{1}{x} ) = 7 \\ now \\ (x + \frac{1}{x} ) ^{2} \\ (7) ^{2} (given) \\ 49 \\ again \\ {x}^{2} + ( \frac{1}{x} ) ^{2} \\ (x + \frac{1}{x}) ^{2} - 2 \times x \times \frac{1}{x} \\ (7) ^{2} - 2 \\ 49 - 2 \\ 47$
