Question

if you wrote the number 0.0009763 as a single digit times a power of ten, would the exponent be positive or negative? explain.

Answer 1

10^n means to multiply by 10

10^-n means to divide by 10 or multiply by 1 / 10

So .0009763 means 9.763 / 10000 = 9.763 * 10-4

can also write as 9.763E-4

If multiplying then the power of 10 would have to be negative
