Answer 1

x^12

Step-by-step explanation:

just add the exponents when multiplying

Answer 2

`\Huge\boxed{\mathsf{\Rightarrow X^1^2}}`

Explanation:

TO SOLVE:

With exponent rule.

SOLUTIONS:

First, use exponent rule.

EXPONENT RULE:

`\displaystyle \mathsf{\Rightarrow A^B*A^C=A^B^+^C}}`

`\displaystyle \mathsf{X^5^+^7}}`

Solve.

Add the numbers from left to right.

`\displaystyle \mathsf{7+5=\boxed{\mathsf{\Rightarrow 12}}}}`

`\Rightarrow \Large \boxed{\mathsf{X^1^2}}}`

So, the final answer is x¹².
