1 x 128, 2 x 64, 4 x 32, 8 x 16, 16 x 8, 32 x 4, 64 x 2, 128 x 1
The LCM of 128, 162 & 100 is 259200 128 = 27 162 = 2 x 34 100 = 22 x 52 lcm = 27 x 34 x 52 = 259200
Well, darling, that's an easy one. If you're looking for two numbers that multiply to 128, it's 8 times 16. Voilà! Math is a piece of cake when you have me around.
1 x 128, 2 x 64, 4 x 32, 8 x 16, 16 x 8, 32 x 4, 64 x 2, 128 x 1 = 128
128 = 1 x 128, 2 x 64, 4 x 32, 8 x 16.
x = 64 64 + 64 = 128

The only prime factor of 128 is 2 because 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
Factors of 128 in pairs: 1 x 128, 2 x 64, 4 x 32, 8 x 16.
128 = x7 (we see that x > 0, since x is raised to an odd power) 27 = x7 (this is true only when x = 2) 2 = x Remember that a logarithm is an exponent. The statement 128 = x7 is equivalent to logx 128 = 7. logx 128 = 7 log 128/log x = 7 (or reverse the both sides) log x/log 128 = 1/7 (multiply by log 128 to both sides) log x = log128/7 (or use base 10 for the logarithm) log10 x = log128/7 (write the equivalent statement) 10log 128/7 = x 2 = x or use the natural log, ln. 128 = x7 ln 128 = ln x7 ln 128 = 7ln x (ln 128)/7 = ln x e(ln128)/7 = elnx (elnx = x ) 2 = x

76.5625% how to figure this out: 90/128=x/100 100*98/128=x x is the percentage which is equal to 76.5626
find x when, 2x=128 2x=128 /2 /2 x=128 /2 x=64 then check your answer by doing the following if x=64, then what is 2x? 2(64)=? or 2 * 64=? or 2 x 64=? 2 times 64 equals 128!
128 = 2 x 64 = 4 x 32 =8 x 16
