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! :)
