Logₐ(y) = x is the same thing as a^x = y

Logarithms asks the question "How many times do I need to raise a to get y?"

log₄(16) = x
x = 2

Test our solution.

4^2 = 16

Our solution checks out.

What is the solution of the equation 8(3x+4)=2(12x-8)?
Maslowich
There is no solution because after you distribute, you have 24x in both sides. When moved to the other side, they cancel. Therefore, you are left with 24=-16 which isn’t true.

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15
Inessa [10]

Answer:

\frac{4+16a^3+23a^3}{a^2}

Step-by-step explanation:

Given

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15

Required

Simplify

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15

Collect Like Terms

1/a^2 + 1/a^2 + 2/a^2-3a-5a-8a+2+6+15

1/a^2 + 1/a^2 + 2/a^2-16a+23

Add Fractions:

\frac{1+1+2}{a^2} + 16a + 23

\frac{4}{a^2} + 16a + 23

This can be further expressed as:

\frac{4+16a^3+23a^3}{a^2}
