Question

Find the equivalent exponential expression. (7^4)^5

Answer 1

To solve this, we need to know a formula. The formula is:

$(x^{y} )^{z} = (x^{yz})$

That being said, now we can simplify. $(7^{4} )^{5} = (7^{4*5})$=
$7^{20}$

Answer 2

Hi!

To solve exponental equations, multiply the exponents.
4·5=20

The answer is $7^{20}$

Hope this helps! :)
