you can solve these problem in different ways. First you can multiply 1 by 36 then divide the answer with 4 which you get the answer as 9 Second you can simplify 36 by 4 and get the answer to be the same.=9
There are two ways to solve this. One is using the definition of logarithms: solve the equation 4x = 16. This can be done by inspection, in this case. The other is to use a change-of-base, to change to a base your calculator can handle. For example, changing to base e: log416 = ln(16) / ln(4)
x=4From superscot85: How you solve it is to subtract 4 from each side leaving x = 4
7*7 + 7 - 7 is one of many ways to do this.
You can solve this problem by doing the equation for combinations: which in this case is 4x3x2x1. So the answer is 12 different ways. no actually the answer is 24 different ways because 4x3x2x1=24 same as 4!
That's one of 120 ways in which the numbers from 1 to 5 can be rearranged.

There are several ways to solve x2-x-12. The easiest way, if you have a graphing calculator, is to put y = x2-x-12 and y = 0 into the graph and then solve for the intercepts. A way to do it without a graphing calculator is by factoring. x2-x-12 factors into (x-4) and (x+3). Then set (x-4) and (x+3) each equal to zero and solve. (x-4)=0 becomes x=4. (x+3)=0 becomes -3. Therefore, the answers are -3 and 4.

Easy! if -a = -4 then a = 4!!

2y = 4 (divide both sides by 2 to solve) y = 2
How many times does 4 go into 2 you ask? Here we will explain two ways of looking at this problem to solve it. "How many times does 4 go into 2?" is the same as asking "How much is 2 divided by 4?" Thus, the answer can be calculated as follows: 2/4 = 0.5
