Answer:

1.) 7. (7 x 7 = 9)

2.) IDK, sorry

3.) 8/27

Apply the product rule to 2/3

2^3/ 3^3

Raise 2 to the power of 3.

8/27

4.) 9

1. Exponentiation: 3 ^ 4 = 81

2. Exponentiation: 3 ^ (-2) = 0.111111111111 = 1/9

3. Multiple: the result of step No. 1 * the result of step No. 3 = 81*1/9  = 81 · 1/1 · 9  = 81/9  = 9 · 9/1 · 9  = 9

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(81, 9) = 9. Cancelling by a common factor of 9 gives 9/1.

In words - eighty-one multiplied by one ninth = nine.

4. Exponentiation: 3 ^ 0 = 1

5.Multiple: the result of step No. 4 * the result of step No. 5 = 9 * 1 = 9

5.) 1/125

5 ^ (-3) = 0.008 = 1/125

6.) IDK, sorry

What is the following expression mulituply out (5x-6y)(5x-6y)
Anna007 [38]

Answer:

25x^2 - 60xy + 36y^2

Step-by-step explanation:

(5x - 6y) ( 5x - 6y)

Use foil to get the result when this is expanded.

F: (first term in each factor): 5x*5x = 25x^2

I:  Use the last term first factor multiplied by first term second factor

- 6y * 5x = - 30xy

O:Outside. Use first term first factor and last term second factor

5x * -6y = - 30xy

L: last term in both factors -6y * - 6y = 36y^2

All them together

25x^2 - 30xy - 30xy + 36y^2

and combine

25x^2 - 60xy + 36y^2
