Simplify these exponents

1) 4^2
2) 6^2
3) 5^3
4) 2^6​

Answers

Answer:

1.) 16

2.) 36

3.) 125

4.) 64

Step-by-step explanation:

multiply the base however many time it says so 4^2= 4*4=16 2^6=2*2*2*2*2*2=64

Answer:

Aight so...

1) 16

2) 36

3) 125

4) 64

Step-by-step explanation:

So when you have a number being squared or with an exponent of 2, all you're doing is multiplying it by itself. Same thing if it's being cubed, or it has an exponent of 3. You'll multiply it by itself 3 times. For example, 6^2 is 36 because 6 x 6 is 36. Hope this helps, I dunno if it did but I hope so ^^

Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10

Answers

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Step-by-step explanation:

5x - 3x = 10

2x = 10  Divide by 2

x=5

2(2x - 1) = 46   Distribute the 2

4x - 2 = 46  Add 2

4x = 48  Subtract by 4

x = 12

6x - 15 = 75  Add 15

6x = 90  Divide by 6

x=15

x + x - 10 =26  Add the x's together and the 10

2x = 36  Divide by 2

x = 18

This is (compound) probability: Picking two numbers from 1-10 and getting a multiple of 3 both times.

Answers

Answer:

There are 10 counters in the bag and you want the 4

As their is only one for the probability is

1/10

There are now 9 counters left in the bag.

You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)

There are only four even counters in the bag of nine counters so the probability is

4/9

As you want both of these to occur, you need to multiply them

1/10 x 4/9 = 49/90

Step-by-step explanation:

The probability of getting a multiple of 3 both times is 2/30.

What is the probability?

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

We are randomly picking two numbers from 1-10.

Multiple of 3 between 1 and 10 are 3, 6, 9.

To find the probability:

Here, we are considering the that the numbers are chosen without replacement.

The probability of getting a multiple of 3 both times,

= 3/10 x 2/9

= 6/90

= 2/30

Therefore, the probability is 2/30.
