5 x 0 = 0 5 x 1 = 5
With exponents: (5 x 106) + (0 x 105) + (0 x 104) + (5 x 103) + (0 x 102) + (0 x 101) + (5 x 100)Without exponents: (5 x 1000000) + (0 x 100000) + (0 x 10000) + (5 x 1000) + (0 x 100) + (0 x 10) + (5 x 1)
6 x 0 x 5 = 0 (6 x 0) = 0 (0 x 5) = 0 So your answer is zero.
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
5,500,000 = (5 x 100000000) + (0 x 10000000) + (5 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
x squared +5x=0 x(x+5)=0 In this situation x=0 or x=-5 If x=0 0(0+5)=0 note: any number multiplied by zero is zero If x=-5 -5(-5+5)=0 -5(0)-=0
it is 0 because 6 x 0 =0 then 0 x 5 =0
5 x 0 = 0 5 x 1 = 5
With exponents: (5 x 106) + (0 x 105) + (0 x 104) + (5 x 103) + (0 x 102) + (0 x 101) + (5 x 100)Without exponents: (5 x 1000000) + (0 x 100000) + (0 x 10000) + (5 x 1000) + (0 x 100) + (0 x 10) + (5 x 1)
6 x 0 x 5 = 0 (6 x 0) = 0 (0 x 5) = 0 So your answer is zero.
4x2 - x - 5 = 0 4x2 + 4x - 5x - 5 = 0 4x(x + 1) - 5(x + 1) = 0 (4x - 5)(x + 1) = 0 4x - 5 = 0 or x + 1 = 0 4x = 5 or x = -1 x = 5/4 o x = -1
x2 - 2x - 10 = 5 x2 - 2x - 15 = 0 (x - 5)(x + 3) = 0 x - 5 = 0 and x + 3 = 0 So, x = 5 and x = -3
5 ^x = 0 5 = root square 0 5=0
55,400,000 = (5 x 107) + (5 x 106) + (4 x 105) + (0 x 104) + (0 x 103) + (0 x 102) + (0 x 101) + (0 x 100)
5,500,000 = (5 x 100000000) + (0 x 10000000) + (5 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
x = -1/2 or -5 2x2 + 11x + 5 = 0 ⇒ (2x + 1)(x + 5) = 0 ⇒ (2x + 1) = 0 → x = -1/2 or (x + 5) = 0 → x = -5
6 x 0 x 5 = 0 Because any number multiplied by 0 is equal to zero, 6 x 0 = 0 and then 0 x 5 = 0.
