Use the "x to the y" key, found right below the "e" key.

To calculate invsin, hit the (2nd) button and then the (sin) button and then enter the number.

Similar for cos and tan.

There are two ways:

First way:  multiply the original number by  2  and then divide that answer by  3.

Second way:  divide the original number by  3  and then multiply that answer by  2.

-61  =  -7 ( 3b + 1 ) - 6b

Use the distribuitve property on -7 ( 3b + 1)   to get    -7(3b)  +  -7(1)    to get    -21b - 7

-61  =  -21b - 7 - 6b  

Combine the  -21b - 6 b  to get  -27b

-61  =  -27b - 7

Add 7 to both sides:

-61 + 7  =  -27b - 7 + 7

-54  =  -27b

Divide both sides by -27   -->  -54 / -27  =  2

2  =  b

In an equation such as  y  = 2x + 1,  

the x is the "independent" variable because you can enter any number for x,

while the y is the "dependent" variable because its value is dependent upon the number that you entered for x.

In an experiment, such as determining how many calories that you burn per hour of one particular type of exercise,

the numer of hours that you exercise is the independent variable,

while the number of calories burned is the dependent variable. 

If you work for a wage, the number of hours worked is the independent variable while the amount earned is the dependent wage.

On the calculator on this site, the negative button and the minus button is the same button.

If you give back $1 for every $2 that you make, you will have to give back half the money that you've made.

How much is one-half of $4000.00? That's the amount that you will have to give back.

To write  14 3/4   as a common fraction:

   --  to get the numerator, multiply 14 x 4 and add 3  -->  56 + 3 = 59

   --  the denominator is 4

Therefore,  14 3/4  =  59 / 4

Now:  to divide, multiply by the reciprocal  (the reciprocal of  3  is  1 / 3)

   59 / 4 ÷ 3     --->   59 / 4  x  1 / 3

To solve, multiply the numerators together ( 59 x 1 ) to get 59

and multiply the denominators together (4 x 3 ) to get 12

So, the answer is 59 / 12

To write this answer as a mixed number: Divide  59  by  12  to get a quotient of  4  and a remainder of  11:

4 + 11 / 12

Do you mean √1 x (10^19)   which is  1 x ( 10^19 )  which is just  10^19     (a 1 followed by 19 zeroes)

or  √( 1 x 10 ) ^ 19   =   √10 ^ 19        which is 3 162 277 660  (approx) 

Mixed number are like this:  5 1/4

You can change it into a decimal by dividing 4 into 1 to get .25 and then add that to 5 to get  5.25

You can change it into a common fraction by multiplying the 5 times 4 and then adding the one,

to get 21 / 5.
