21 + (4 x 2) = 29 (21 + 4) x 2 = 50
21 x 21 = 441
? + 29 = 50 The way to find '?' is to take the 29 from 50. 50 - 29 = 21 ? = 21 21 is the answer.
Notes: 1 cup = 8 oz. & 1 oz. = 29.57 cc 8 x 29.57 = 236.56 cc 50 / 236.56 = .21 cups Answer: .21 cups
21
They are:1 x 212 x 213 x 214 x 21....48 x 2149 x 2150 x 21
Expressed as a percentage, 21/50 x 100 = 42 percent.
50 = 21 x 52
Use a factor tree. 50 25,2 5,5,2 2 x 5 x 5 = 50
350.
e^50 = 5.2 X 10^21
The prime factorization of 50 using exponents is 21 x 52
21 + (4 x 2) = 29 (21 + 4) x 2 = 50
To solve common multiples, take the prime factorization of each number. As an example, lets look at 14, 50, and 70... 14 = 21 x 71 50 = 21 x 52 70 = 21 x 51 x 71 To find the least common multiple, take each factor present, with the maximum encountered value of its exponent, and multiply them together... 21 x 52 x 71 = 350. The LCM of 14, 50, and 70 is 350. Not asked, but answered for completeness, to find the greatest common divisor, take each factor present, with the smallest encountered value of its exponent, and multiply them togother. Note that a missing factor effectively has an exponent of zero... 21 x 50 x 70 = 2. The GCD of 14, 50, and 70 is 2.
21 is not a prime factor, it is 3 x 7
3.14 times 7= 21.98 (21 and 49/50)
21 multiplied by 50 is 1,050.
