root x=x^(1/2) and 4x =4 x^1 you add the exponents then integrate as usual. The answer you should get is 4.

The area of rectangles (including squares) is given by length x width. for the square 20 x 20, its area is 20 x 20 = 400 For the rectangle 10 x 30, its area is 10 x 30 = 300 If the shapes are divided up into 10 x 10 squares, it can be seen that the square has four of them, where as the rectangle will only have three: ................................................. ......20 x 20..........10 x 30.......... .....---------.......-------------.... .....|.....|.....|......|.....|.....|.....|.... .....|.....|.....|......|.....|.....|.....|.... .....|---+---|......-------------.... .....|.....|.....|.............................. .....|.....|.....|..Each little square.. .....---------.......is 10 x 10......... .................................................

integrate of x is 1/2x^2. integrate of 1 is x

Each 10' x 10' tile measures 100 square feet and 3300 square feet divided by 100 square feet gives the answer that 33 tiles are needed.

simplify the square foor of 49 times x to the third time y to the sixth times the absolute value of z squared

I can't integrate a-x /x-3 ?

x/sqrt(x)=sqrt(x) integral sqrt(x)=2/3x3/2

x/3000 = 10 x = 10 (3000) x = 30,000

I'm guessing you mean: √250 - √40/2 = √(25 x 10) - √(4x10)/2 = √25 x √10 - √4 x √10/2 = 5 √10 - 2 √10/2 = 5 √10 - √10 = 4 √10

4 x square root of 10 minus square root of 10 = 3 x square root of 10.

√360 / √30 = (√3 x √10 x √12) / (√3 x √10) = √12 I think that's the most simplified result. If anyone can see an integer in there be my guest.

100 square units (10 x 10 = 100).

10

replace square root o x with t.

10

The square root of 100 is: ± 10, because 10 x 10 = 100 and -10 x -10 = 100The square root of 100 is 10.

x = -10 or x = 10
