Ineed the answer and how you got to it . (2.5 x 10^-10)(7 x 10^-6)

The second number is called the base . It must always be 10 in scientific notation. The base number 10 is always written in exponent form. In the number 2.5 x 1011 the number 11 is referred to as the exponent or power of ten.

so that equals 166560 if you wrote the problem the way i see it

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
