Answer:
it gives you -140 if you multiply all of them
I believe it’s 30,180,000
First do 4% -> 0.04x15=0.6
0.6+100=100.6x300,000
But then again I’m not too sure so double check
2√50 × 3√32 × 4√18
=2(5√2) × 3(4√2)× 4(3√2)
=2(5)(2)(3)(4)(4)(3√2)
=2880√2
We have
(a + b)² = a² + 2ab + b²
so that with a = x² and b = 5, we have
x⁴ + 10x² + 25 = (x² + 5)²
Next, we have
a² - b² = (a - b) (a + b)
so that with a = x and b = √5 i,
x² + 5 = x² - (-5) = (x - √5 i) (x + √5 i)
So, the complete factorization over the complexes is
(x - √5 i)² (x + √5 i)²
