Question

√y18

please solve this one for me with explication

Answer 1

Answer:
`y^9`

This is the same as saying y^9

===================================================

Step-by-step explanation:

When we apply the square root to the expression
`a^(2b)`, we end up with
`a^b`

`\sqrt{a^(2b)} = a^b`

The exponent 2b divides in half to get b

Based on that rule, we can then say:

`\sqrt{y^(18)} = y^(18/2) = y^9`
