6 0

Answer:

4x - 3y + 6z.

Step-by-step explanation:

He wrote 62 instead of 6z on the first line.

He made 2 mistakes on the last line:

He didn't subtract the x terms, there was no term = 5.

The -3y + 6z does not simplify to 3yz,  the terms have an add process not a multiply.

The correct solution is

5x - x - 3y + 6z

= 4x - 3y + 6z.

What is (-3)^-9 times (-3)^5
otez555 [7]

Answer:

1/80 or 0.01234568

Step-by-step explanation:

Exponentiation: (-3) ^ (-9) = -5.08052634253E-5 = -1/

Exponentiation: (-3) ^ 5 = -243

= -1/

19683

19683 · 1

= 243/

19683

= 1 · 243/

81 · 243

= 1/
