-1 * 3 * 3 * 3 * 3 * x * x * x = -81x3

3x3x3x3x3= 9x9x3= 81x3= 243

244 1x3=3, 3x3=9, 9x3=27, 27x3=81, 81x3=244

you multiply 9x9 and you get 81 then you multiply 81x3 = 243 CHEESE! is it chicken pie? thats one big pie.

The next number is 243, because 81x3=243.

its an exponential series. 3^0=1 3^1=3 3^2=9 3^3=27 3^4=81 3^5=X more of how to solve it then the answer [if your still stuck think of it as 81x3=X] in laymans terms 243, times it by 3 each time.

A "power" means the number of times you multiply the base number by itself.In your question "6 to the power of 3" means 6 x 6 x 66 multiplies by itself 3 times.You can type 6*6*6 into your calculator... but what if you were asked to find:5 to the power of 20.that's 5 x 5 x 5 x 5..... 20 times. I wouldn't want to type that into my calculator, and I'm sure you wouldn't either!Thankfully, there's an easier way.5 x 5 x 5..... x5, 20 times can be written as 5^20Similarly, We can write 6 x 6 x 6 as 6^3. We read 6^3 as "six, raised to the power of three" or "six cubed" or "six raised to the third power".6 is our base number, and 3 is our power.So, you can type 6^3 into your calculator to find out what 6 to the power of 3 is.You should find the ^ key on your calculator, ask your teacher or parents if you can't find it. The ^ is called a "caret", it sounds the same as "carrot".Sometimes you're asked to find for example, 3 squared, or 3 to the 2nd power. While you can type in 3^2 into your calculator, you'll get the same answer as 3x3, or 32 .In fact, there's a square button on your calculator too! Sometimes the button looks like x2but some people say that 3 to the power of 6 is 2187 this is how they do it 3x3=9x3=27x3=81x3=243x3=729x3=2187 this may aso b right depending on how you get taught to do it
