A: When you multiply two numbers, their exponents add. 
So, 64^{\frac{1}{2}} * 64^{\frac{1}{2}} = 64^{\frac{1}{2} + \frac{1}{2}} = 64^{1} = 64

Since 64^1/2 multiplied by itself is 64, then it is the square root of 64.

B: The area is irrational. 7 * √7 is irrational.

1.  
64^1/2 * 64^1/2  = 64^(1/2 + 1/2) = 64^1  = 64

2. Area = l * w  = 7 * √7  =  7√7

√7 is irrational  so 7√7 is irrational also

If f(×)= x^1/2-× and g(×) = 2x^3-×^1/2-×, find f(×)-g(×). Pleade ASAP
Anettt [7]

Answer:  

-2x^3 + 2x^(1/2)

Step-by-step explanation:

step one- plug in the values of each in f(x) - g(x)

x^(1/2)-x - (2x^3-×^(1/2)-x) ; g(x) is in parentheses bc we need to distribute the negative

x^(1/2)-x-2x^3 + x^(1/2) + x ; combine like terms (letters with the same exponents) ; the x's cancel, and the x^(1/2) + x^(1/2) combine to form 2x^(1/2); the -2x^3 remains

you should get

-2x^3 + 2x^(1/2)

zlopas [31]

Answer: B. -2/3 the amount of water decreases every 3 minutes!

Step-by-step explanation:

B because it starts with 14 gallons with 0 minutes and the slope goes go down 2 and run 3 so therefore, the answer is B because from 14 gallons and 0 minutes it goes to 3 minutes 12 gallons and 6 minutes and 10 gallons so it decreases 2 gallons everything 3 minutes!

Hope this helps please give brainliest!
