Question

What is the product 4^3* 4^-3

Answer 1

Hello there!

$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \Downarrow\\ \\ \left[\begin{array}{ccc}4^3\end{array}\right] = 4*4*4=64 \ . \ . \ . \ . \ so \ far$

Then . . . .

$\left[\begin{array}{ccc}4^-3=0.015625\end{array}\right]$

$(we \ the \ add \ both \ 64*0.015625)$

$\left[\begin{array}{ccc}\boxed{64*0.015625}\end{array}\right] = \boxed{\bf{1}}$

Your correct answer is 1.

Answer 2

Hey there! :D

Take care of the exponents. 

4^3= 4*4*4 

4^3= 64

4^-3

Make it a fraction to make the power positive. 

$\frac{1}{4^3}$

Now, simplify. 

$\frac{1}{64}$

64* 1/64= 1

The answer is 1. 

I hope this helps!
