Answer:
1/5 to the 18 power or
2.62144 x 10 to the -13 power.
Or just simply 5 to the -18 power
Step-by-step explanation:
Well, when you want to make 15 a percentage, You need to know of what, for an example, 20 percent of 100 is 20% percent because 20/100= 0.20 which equals 20%. What is 15 of? Fill in the blank. 15 percent of ___=? which would be 15/?
Here you go -12.4 - 5.75 x is your Answer
So, x = 13, x = √3 and x =7i.
now, recall that for an EVEN radical, there are two possible roots, namely is say √3 is say hmmm some value "a", that means that a*a = √3, however, -a*-a is also √3, therefore, ±√3 are two valid values, and therefore -√3 is another one.
now.... keep in mind that, complex solutions or roots, never come all by their lonesome, their sister is always with them, the conjugate, so, for 7i or namely 0 + 7i, her sister is always around, 0 - 7i, which is the other root.
