Question

rewrite using a single positive exponent. four to the power of 7 over 4

Answer 1

We are given the expression

$\frac{4^7}{4}$

We must recall a property of exponents:

$\frac{4^x}{4^y}=4^{x-y}^{}$

In this case, x=7 and y=1 (the exponent is hidden but it's 1)

Thus, applying the above property:

$\frac{4^7}{4}=4^{7-1}=4^6$
