Do it exactly as the question directs:
Four times means you're multiplying SOMETHING by four, so go ahead and write a four down:
4
Times the square root of means you're multiplying 4 by the square root of SOMETHING, so go ahead and put that radical next to the four:
(note that there is no radical sign on here, but x^(1/2) is the same thing as the square root of x, sooo):
4(SOMETHING^(1/2))
Now it tells us that SOMETHING is x less than 20, which means you're subtracting 20 by x, or:
SOMETHING = 20-x.
SO, putting 20-x instead of something into the expression leave us with:
4((20-x)^(1/2))
or, "four times radical twenty minus x."
Hope that helps a little.
square root 2 times square root 3 times square root 8
The square root simplifies to six times the square root of five. The decimal form of that is approximately 13.41640786
0
It has a rounded square root of 18.03
5.8259
square root 2 times square root 3 times square root 8
Square root of 2 times the square root of 46 = ±9.59166305
Its the square root of 2 times x Ambiguous. More clear is x times square root of 2
The square root of two times the square root of two equals two
98 is 49 times 2 so the square root of 98 is the square root of 49 times the square root of 2. But the square root of 49 is 7 , so the answer is 7 times the square root of 2.
It is equal to: 2 times the square root of 30
No because the square root of 98 is 7 times the square root of 2
24, because the square root of eight times the square root of eight, is eight. the square root of any number, squared, is the original number. then 8 times 3 is 24
Do the multiplication, then take the square root. After the multiplication, you get 28x4y2. The square root of 28 is 2 times the root of 7, the square root of x4 is x2, and the root of y2 is y. So, the final result is 2 times square root of 7, times x2y.
The square root simplifies to six times the square root of five. The decimal form of that is approximately 13.41640786
The square root of 12 equals the square root of 4 times 3. The square root of 4 is 2. The square root of 12 equals 2 times the square root of 3.
139, the square root of 19321 is less than 140.
