Answer 2

Answer:

0.34 × 0.34 - 0.66 × 0.66 = -0.32

Step-by-step explanation:

We are given,

0.34 × 0.34 - 0.66 × 0.66

0.34² - 0.66²

We know that,

a² - b² = (a + b)(a - b)

So,

0.34² - 0.66²

= (0.34 + 0.66)(0.34 - 0.66)

= 1 × (-0.32)

= -0.32

Thus,

0.34 × 0.34 - 0.66 × 0.66 = -0.32

Hope it helped and believing you understood it........All the best
