The answer would be 4 . This is expressed by the logarithmic equation log 2 ( 16) = 4 , read as "log base two of sixteen is four". 2 4 = 16 log 2 ( 16) = 4. Both equations describe the same relationship between the numbers 2 , 4 , and 16 , where 2 is the base and 4 is the exponent. The difference is that while the exponential form isolates the ...Math is a powerful tool for global understanding and communication.

To solve your equation using the Equation Solver, type in your equation like x+4=5. The solver will then show you the steps to help you learn how to solve it on your own. So we can define the three types of fractions like this: Proper Fractions: The numerator is less than the denominator. Examples: 1/3, 3/4, 2/7. Improper Fractions: The numerator is greater than (or equal to) the denominator. Examples: 4/3, 11/4, 7/7. Mixed Fractions: A whole number and proper fraction together.Sometimes in math we describe an expression with a phrase. For example, the phrase. " 2 more than 5 ". can be written as the expression. 2 + 5 . Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable). For example,

Exponents. The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Some more examples: Let's take an example of a simple formula. On the worksheet, click the cell in which you want to enter the formula.

Then try 12.5% of 43.75 (shows that before a 12.5% reduction it was 50.) Compare 100 to 110, and see that to go from 100 to 110 is a 10% increase, but to go from 110 back down to 100 is a 9.09% decrease (not a 10% decrease)Try using a range of assessment strategies, such as think-pair-share, peer interviews, journaling, open-ended questions, and storytelling instead, which don't ...Now subtract 6 from each part: −12 < −2x < 6.
