Question

show that : [-3/5]^2=9/25​

Answer 1

Answer:

Step-by-step explanation:

$(-3/5)^{2} = (-3)^{2} / (5)^{2} \\=9/25$

Answer 2

Step-by-step explanation:

${ \frac{ - 3}{5} }^{2} = \frac{ (- 3) \times (- 3)}{5 \times 5}$

The rule implied here states here that the product of an even number of negative numbers is positive . This is why -3 when multiplied by -3 yields in 9 instead of -9 .

${ \frac{ - 3}{5} }^{2} = \frac{9}{25}$
