No, a negative x a negative = a positive. (-5) x (-2) = 10
-5 x 10 = -50
When one of the factors is less than or equal to 1, and the other is positive. Examples: 1 x 9 = 9 0 x 5 = 0 -1 x 10 = -10 If both are negative, it doesn't work: -10 x -10 = +100
The question could mean 5 divided by (10 raised to the negative 3),or it could mean (5 divided by 10) raised to the negative 3 .5/(10)-3 = 5 x (10)3 = 5,000===========================(5/10)-3 =( 1/2)-3 = 23 = 8
1*10^-5 = 1/100000 or 0.00001
Positive minus a negative = positive plus a positive two negatives make a positive 3- (-1) = 3 + 1 = 4 5- (-7) = 12

x*(-5) = 10 Divide both sides by 5: x*(-1) = 2 Multiply both sides by -1 and remember that (-1)*(-1) = +1 x*(+1) = -2 x = -2
No, a negative x a negative = a positive. (-5) x (-2) = 10

The pH of a solution with an H3O+ concentration of 1 x 10^-5 M is 5. This is because pH is defined as -log[H3O+], so by taking the negative logarithm of 1 x 10^-5, the pH is 5.
-5 x 10 = -50
0.00001 or 1 over 100,000
256-5 = 1/2565 = 9.094947 x 10-13 approximately,
1 x 101 = 10 1 x 100 = 1 1 x 10-1 = 0.1 1 x 10-2 = 0.01 1 x 10-3 = 0.001 1 x 10-4 = 0.0001 1 x 10-5 = 0.00001 1 x 10-6 = 0.000001 1 x 10-7 = 0.0000001 1 x 10-8 = 0.00000001 1 x 10-9 = 0.000000001 1 x 10-10 = 0.0000000001
negative times a negative is positive. (- x - = +) Ex., -2 X -5 = 10
