Multiplying and Dividing Exponents are very easy.
When they are multiplied, we add the exponent numbers together.
When they are divided, we subtract the exponent numbers.
In this example,
/
We can conclude that
is 1 because,
any number to the power of 0 is 1
=
take the exponents alone:
-18+3 (Because it is multiplication) =-15

Answer:
x = 24/13
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
18/13 = 3/4x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 3/4: x = 24/13
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 18/13 = 3/4(24/13)
- Multiply: 18/13 = 18/13
-19u + 11 = -20u
Add 19u to both sides.
11 = -u
Divide both sides by -1.
-11 = u
Answer:
-3
Step-by-step explanation:
start by opening the brackets 4(4x+1)=(3x-46-x)+8
16x+4=3x-46-x+8 then put like terms together =
16x-3x+x=-46+8-4
14x=-42 divide all over by 14
=-3
