4^3 x 4^-7

5 answers

To simplify the expression 4^3 x 4^-7, we first calculate the exponents separately.

4^3 = 4 x 4 x 4 = 64

4^-7 = 1 / 4^7 = 1 / 16384

Now, we multiply the two results together:

64 x (1/16384) = 64 / 16384 = 1 / 256

Therefore, 4^3 x 4^-7 is equal to 1/256.
A) 4^-10
B) 4^-4
C) 4
D) 4^10
To simplify each expression:

A) 4^-10 = 1 / 4^10 = 1 / 1048576

B) 4^-4 = 1 / 4^4 = 1 / 256

C) 4 = 4

D) 4^10 = 1048576

Therefore, the simplified expressions are:

A) 1 / 1048576
B) 1 / 256
C) 4
D) 1048576
So what is the answer
The answer is:

B) 4^-4 = 1 / 256
