Question

Can you help me with this problem​

Answer 1

Answer:

$7 {x}^{6} {y}^{4}$

Step-by-step explanation:

to understand the solving steps

you need to know about

• $\sqrt{xy} < = > \sqrt{x} \sqrt{y}$
• PEMDAS
• $\sqrt{ {x}^{y} } < = > {x}^{ \frac{1}{y} \times 2}$

let's solve:

$\sqrt{49 {x}^{12} {y}^{8} }$

$\sqrt{ {7}^{2} } \sqrt{ {x}^{12} } \sqrt{ {y}^{8} }$

$7 ^{ \frac{1}{2} \times 2 } \times {x}^{ \frac{1}{2} \times 12 } \times {y}^{ \frac{1}{2} \times 8 }$

$7 {x}^{6} {y}^{4}$
