It does if the x values don't repeat it they repeat it doesn't
Answer:
16. D
17. 5^-1 · 5^-1 and 25^-1
8^0 · 8^3 and 8^3
Step-by-step explanation:
When you multiply two same numbers with exponents, just think of it as adding up exponents.
When you divide two same numbers with exponents, just think of it as subtracting exponents.
If a parenthesis has an exponent outside, then every exponent inside the parenthesis will be multiplied by that outside parenthesis.
(5^-1)^-2 · 5^3 ÷ 5^7
5^2 · 5^3 ÷ 5^7
5^5 ÷ 5^7
5^-2
When exponents are negative, you have to flip them or put them on the other side
5^-2 = 1/5^2 = 1/25
Let's try to find the equivalent pairs
6^7 ÷ 6^-2 = 6^5
6^9 = 6^5 Not equivalent
(6^3)^0 = 6
6^0 = 1 (Any number with a zero exponent is always 1)
1 = 6 Not equivalent
5^-1 · 5^-1 = 25^-1
5^-2 = 25^-1
Flip em
1/5^2 = 1/25
1/25 = 1/25 Equivalent
8^0 · 8^3 = 8^3
8^3 = 8^3 Equivalent
4^-3 ÷ 4^2 = 4^5
4^-5 = 4^5 Not equivalent
Answer:
negative because any positive number multiplied by a negative number will be negative, the only way to make it positive is to multiply a negative number by another negative number.
Step-by-step explanation:
You replace x with 3 and y with -2 so
3-3(-2)=9
the answer is D.9
Answer:
see below
Step-by-step explanation:
12x+24x+18 = 36x+24-6
Combine like terms
36x+18 = 36x+18
Subtract 36x from each side
36x+18-36x = 36x+18-36x
18 = 18
This is always true, so the equation is true for all values of x
