Answer:
105
Step-by-step explanation:
<em>Greetings from Brasil...</em>
Here's our problem:
From potentiation properties:
Mᵃ ÷ Mᵇ = Mᵃ⁻ᵇ
<em>division of power of the same base: I repeat the base and subtract the exponents</em>
<em />
So, in our problem
= 12³ ÷ 12⁷
12³ ÷ 12⁴ = 12³⁻⁷
12⁻⁴
We also know about another property: P⁻ⁿ = (1/Pⁿ) so
12⁻⁴ = (1/12⁴)
Answer:
x³ + x - 3
Step-by-step explanation:
f(x) + g(x)
(x³ + 2) + (x - 5)
x³ + 2 + x - 5
x³ + x + 2 - 5
x³ + x - 3
Given:
To find:
The values of x.
Solution:
We have,
(Distributive property)
(Combining like terms)
Add 28 on both sides.
Subtract 10x from both sides.
Divide both sides by 14.
Therefore, the values of x are all real numbers less than 2, i.e., x<2 .
