Answer:
1 + √2
Step-by-step explanation:
∛7 + 5√2
We can write the same thing as,
=> (7 + 5√2)^(1/3) ------ (1)
1st solve 7 + 5√2.
7 + 5√2
=> 1 + 6 + 3√2 + 2√2
=> 1 + 3 * (√2)² + 3√2 * 1 + 1 * 2√2
Rearrange the terms,
=> 1 + 2√2 + 3 * (√2)² * 1 + 3 * √2 * 1²
=> (1 + √2)³
Place the value in (1), it looks like
=> (1 + √2)³^(1/3)
=> (1 + √2)^(3 * 1/3)
=> (1 + √2)¹
=> 1 + √2
