Please read this first: Standard mathematical operations, expressed in Japanese
As described in the question above, there are several approaches to read this. The most simple approach is to read each symbol one by one. This ^ symbol can be read ハット, キャレット or 累乗【るいじょう】.
かっこ エックス たす ワイ かっことじ るいじょう ゼット
More naturally, the expression xn can be read as "xのn乗" (エックス の エヌ じょう; "x to the power of n-th"). With this, you can read it like this:
かっこ エックス たす ワイ かっことじ の ゼット じょう
If you omit かっこ/かっことじ and say it like this:
エックス たす ワイ の ゼット じょう
...it may be taken as x + yz rather than (x + y)z. This may be okay if everyone is actually seeing the expression on a screen or a blackboard.
You can avoid this ambiguity by using 和【わ】:
エックス と ワイ の わ の ゼット じょう
(literally, "x-and-y's sum, to the z-th power")
Note that にじょう is "to the second" or "square" (x2), not n-th power in general (xn).
^2), not exponentiation in general (^n).
