When a number is raised to a negative exponent, it is equivalent to its reciprocal raised to the positive exponent. Therefore, x to the power of -7 is equal to 1 divided by x to the power of 7, or 1/x^7.

When we have x to a negative exponent we can move the x to the denominator and make the exponent positive.
So x-7 is the same as 1/x7
1.0 x 10^-7 What that means is simply 1 divided by -10 x -10 x -10 x -10 x -10 x -10x -10 Power means the little number after the base number and negative just means well negative (minus before the power). Also power means what ever number of power it times by itself by the number shown. So, 5 power 2 is just 25 (5x5), or we call it squared.
To express x to the power of negative 2 as a fraction, you can rewrite it as 1 over x squared. This is because any number raised to a negative exponent is equivalent to its reciprocal raised to the positive exponent. Therefore, x to the power of negative 2 is the same as 1 over x squared.
1.835 x 10 to the negative 4th power in standard notation is 0.0001835
3 times 10 to the 8th power divided by 7 times 10 to the negative 7th power equates to: 4.28571428571
It is the inverse of x to the positive value of that power. So x-a = 1/xa or (1/x)a
