The square root of x-3 plus 5 equals x?
x = 7
What is the square root of X?
Restricting the discussion to real numbers for now. In this case, the square root is only defined for non-negative numbers; the principal square root of a positive number is the POSITIVE square root. For example, both +5 and -5 are square roots of 25, since both - when squared - give you 25. But the positive square root (+5) is called the principal square root, and if you write the square root symbol, that's the number usually meant.
Square root x plus 3 equals 12?
X = 81 sqrt(X) + 3 = 12 ( subtract 3 from each side ) sqrt(X) = 9 (square both sides ) X = 81 ( the square root of 81 is 9 )
What is the square root of x to the power of 3 equal to?
It is x*sqrt(x) or x^(3/2)
How do you factor x to the third power plus 125?
x^(3) + 125 => x^(3) + 5^(3) This factors to (x + 5)(x^(2) - 5x + 5^(2) ) or (x + 5)(x^(2) - 5x + 25) NB The clue is to spot that the constant (125) is a cubic numbers ( 5^(3)). Similarly with other 'cubic factorings'.
What is the area of a square whose sides is 3 x 5 cm?
3 x 5 cm = area 15 square cm BUT a shape 3 x 5 is not a square, it is a rectangle. A square would either be 3 x 3 or 5 x 5 size.
What is 3 square root x - 5 equals 3?
3(x-5)^0.5 = 3 First divide both sides by 3 so that (3(x-5)^0.5)/3 = 3/3 (x-5)^0.5 = 1 Then square both sides ((x-5)^0.5)^2 = 1^2 (x-5)^1 = 1 x-5 = 1 Then add five to both sides x-5+5 = 1 +5 x+0 = 6 x = 6
Can you factor x2-3?
5
How many square feet are 5 x 3 ft.?
There are: 5*3 = 15 square feet
What are two numbers whose sum -6 and product is -5?
-2 and -3Check:(-2) + (-3) = -5(-2)(-3) = 6Thus -2 and -3 are not the required numbers. let's find them: x + y = -6xy = -5 y = -x -6x(-x - 6) = -5-x^2 - 6x = -5x^2 + 6x = 5x^2 + 6x + 9 = 5 + 9(x + 3)^2 = 14x + 3 = (+ & -)square root of 14x = -3 (+ & -)square root of 14x = -3 + square root of 14 or x = - 3 - square root of 14y = -x - 6y = 3 - square root of 14 - 6 or y = 3 + square root of 14 - 6y = -3 - square root of 14 or y = -3 + square root of 14Check:(-3 + square root of 14) + (-3 - square root of 14) = -6(-3 + square root of 14)(-3 - square root of 14) = -5 ?(-3)^2 - (square root of 14)^2 = -5 ?9 - 14 = -5Check also tow other numbers.
What is x in the problem 5 equals x times the square root of 3?
You have : ----------------- 5 = ( x ) ( 3 )^1/2 x = ( 5 ) / ( 3 )^1/2 = +/- 2.887 <-----------------------
How many square meters is 5 x 3?
5 m x 3 m = 15m2
How can you tell by drawing a factor tree whether or not a number is a square number?
A factor tree tells you the prime factorization. The prime factorization can indicate a square number. Square numbers have even pairs of prime factors. 2 x 2 x 3 x 3 is a square number. 5 x 5 x 5 x 5 x 7 x 7 x 7 x 7 is a square number.
How many square feet is 5 feet by 3 feet?
15 square feet
3 square root -5 x 3 square root 9?
3 sqrt -5 = 3 x 5i = 15i; 3 sqrt 9 = 3 x 3 = 9 so full answer is 135i where i is the sqrt of -1
Square root 3 x-5 equals 3?
√(3x - 5) = 3 ∴3x - 5 = 9 ∴3x = 14 ∴x = 14/3
What is greatest square factor of 675?
To find the greatest square factor of 675, we need to break down 675 into its prime factors: 3 x 3 x 3 x 5 x 5. To identify the square factors, we look for pairs of the same prime factors. In this case, we have two 3's and two 5's. Multiplying these pairs together gives us the greatest square factor of 675, which is 3 x 3 x 5 x 5 = 225.
