So the answer is 64.

Answer 7

For the 2 to the 6th power is 64. what about the 2 to the -3 power?

Answer 8

the choices are A.48 B.24 C.12 D.2.

Answer 9

To plug in a negative exponent, put the exponent in parenthesis after the carrot. To solve it without a calculator, rewrite it from x^-n to 1/x^n, so 2^-3 becomes 1/(2^3)

Answer 10

So it is C.12

Answer 11

No. First, multiply 2^6 by 2^-3.

Answer 12

Then add 4. Then multiply by 4.

Answer 19

Ok ,what is 140,200,000,000 written in scientific notation

Answer 20

Scientific notation is just the number with one digit to the left of the decimal and multiplied by 10^n. Example: 342,000,000 in scientific notation is 3.42*10^8. N can be found by seeing how much you move the decimal. First, move the decimal so you have only one digit to the left.

Answer 21

Ok so 3.42*10^8= 342000 ( the 0 is going on and on.)

Answer 22

It would be equal to 342 with 6 zeros. It's to the 8th power because you move the decimal right 8 times. 3.42 -> 342,000,000.
