6a
Step-by-step explanation:
replace x with -a
-2a -6(-a)

6a
Steps to solve:
3^2 • 3^-8 • 3^0
~Apple exponent rule [ a^b * a^c = a^b+c ]
3^2-8+0
~Simplify
3^-6
~Use exponent rule [ a^-b = 1/a^b ]
1/3^6
~Simplify
1/729
Best of Luck!
Answer:
x = 1
Step-by-step explanation:
- 2x^2 + 3 = 5
- 2x^2 = 5 - 3
- 2x^2 = 2
- x^2 = 2/2
- x = \| 1
- x = 1
Pythagorean theorem - a^2 + b^2 = c^2
2^2+3^2 = d^2
d^2 = 13
d= square root of 13
