Question

What are the values of `x, y,and z` in this equation: `(8\times 10^ { x } ) + ( 6\times 10^ { y } ) + ( 2\times 10^ { z} ) = 80620`?

Answer 1

See a solution process below:

Explanation:

We can write the result of the expression on the left as:

`80620 = 80000 + 600 + 20`

`80000 = 8 xx 10^4`

`600 = 6 xx 10^2`

`20 = 2 xx 10 = 2 xx 10^1`

`x = 4`; `y = 2`, `z = 1`
