<h3>
Answer: x*a^2 or a^2*x</h3>
======================================
Work Shown:
a^(b+2) = a^b*a^2 ... break up the exponent
a^(b+2) = x*a^2 ... replace a^b with x
We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.
Answer:
Step-by-step explanation:
The given expresion is
We want to evaluate this expression when x=3i
We substitute to obtain:
We simplify to get
Recall that
This implies that:
Answer:
<h2>x = 14</h2><h2 />
Step-by-step explanation:
7x + 9 + 5x + 3 = 180
7x + 5x = 180 - 3 - 9
12x = 168
x = 168 / 12
x = 14
