Question

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

Answer 1

The first number 2.5 is called the coefficient. It must be greater than or equal to 1 and less than 10.

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 2

If you use a calculator you have to make sure you put your and it's on classic. When you plug your question and push the *10 with the arrow pointing up(^) and do the same with the question times it together and you'll get 1.75*10^-15
