Answer:
1. a^mn= (a^m)^n
2. a^m+n= a^m • a^m
3. 1= a^0
4. a^m • b^m = ab^ m
5. 1/a^n = (a)^m
Step-by-step explanation:
^ means exponent
• means multiply
Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3
