valentina_108 [34]

10x10x10x10x10x10=1000000

{10}^{6}

means 10x10x10x10x10x10

as it's basically saying 10 is multiplied by itself 6 times which gives you 1000000

allochka39001 [22]

Answer:

The answer to your question is 2⁸x²⁰ y²⁴    or    256x²⁰y²⁴

Step-by-step explanation:

Data

                    (2x³y³)⁴ (2x²y³)⁴

To solve this problem, use the law of exponents.

1.- Use the law of Power of a power rule

                    (2x³y³)⁴ (2x²y³)⁴ =           (2⁴x¹²y¹²) (2⁴x⁸y¹²)      

2.- Use the multiplication rule

                      (2⁴x¹²y¹²) (2⁴x⁸y¹²)  =    2⁸x²⁰ y²⁴

3.- The answer is      2⁸x²⁰y²⁴ or we can simplify more like

                                 256x²⁰y²⁴

Amy's penny bank is 1/2 full. After she adds 360 pennies, it is 5/6 full. How many pennies can Amy's bank hold?
stellarik [79]

Answer:

1,080 Pennies

Step-by-step explanation:

This question is fairly simple, you just have to simplify it. You are starting at already half-full, so you can keep that 1/2 in mind. Then, she adds 360 pennies to get 5/6. If you convert 1/2 into 3/6, you can see that 360 pennies fills 2/6 of the piggy bank. So now you can solve two different ways. The first, you can take 360 and multiply it by 3 to get the amount that can fit in the piggy bank, because 2 * 3 = 6 and that would make it 6/6, or 1. The other way would be to divide 360 by 2 to get 1/6 of the piggy bank, or 180. Then you can multiply 180 by 6 to get the entire amount.

Hope this helped ^-^
