Question

a+b=8,ab=15 than what will be the value of b

Answer 1

Answer:

➡ a⁴+a²b²+b⁴ = (a²+b²)² - a²b²

a⁴+a²b²+b⁴ = (a²+b²)² - a²b²Now,

➡ (a² + b²) = (a+b)²-2ab

➡ {(a² + b²)}² = {(a+b)²-2ab}²

➡ a⁴+a²b²+b⁴ ={(a+b)²-2ab}² - a²b²

Since,

• a+b = 8
• ab = 15

Just substitute these values and you will get the answer.

➡ a⁴+a²b²+b⁴ ={(8)²-2×15}² - (15)²

➡ {64-30}²-225

➡ 34²-225

➡ 1156-225

➡ 931
