Answer:
The logarithm of 10,000 with base 10 is 4." 4 is the exponent to which 10 must be raised to produce 10,000. "104 = 10,000" is called the exponential form. "log1010,000 = 4" is called the logarithmic form.
Step-by-step explanation:
Answer:
x = 73
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
(180 - x) + (90 - x) = 124
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 270 - 2x = 124
- Subtract 270 on both sides: -2x = -146
- Divide -2 on both sides: x = 73
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: (180 - 73) + (90 - 73) = 124
- Subtract: 107 + 17 = 124
- Add: 124 = 124
