Determine the value of the expression 4^3•4^-6

Answer 1

To solve this expression, we first perform the exponents:

4^3 = 4 x 4 x 4 = 64
4^-6 = 1 / 4^6 = 1 / 4096

Now, we multiply the two results together:

64 x 1 / 4096 = 0.015625

Therefore, the value of the expression 4^3 * 4^-6 is 0.015625.

Answer 2

what is that as a fraction?

Answer 3

To express the decimal value 0.015625 as a fraction, we can simply write it as a fraction with the decimal number as the numerator and powers of 10 as the denominator.
