Answer 2

Answer:

$1) \: (a+b)²=a²+b²+2ab$

$2) \: simple \: \: interest= \frac{P×R×T}{100}$

$3) \: ( { - 3})^{4} \times {7}^{4} = 3 \times 3 \times 3 \times 3 \times 7 \times 7 \times 7 \times 7 \\ =194481$

$4) \: 0$

$5) \: 7xy \times 6x²y = 42 {x}^{3} {y}^{2}$

$6) \: Discount= Listed \: Price - Selling \: Price \\ </p><p>Discount= Listed \: Price× Discount \: Rate$

$7) Loss = Cost \: Price - Selling \: Price$

$8) Arithmetic \: mean= \: Σ  \frac{xi}{n} \\ Arithmetic \: mean = Σ \frac{(fi \times xi)}{fi}$

$9)Area \: of \: the \: trapezium = \frac{1}{2} h(a + b$

$10)Area \: of \: the \: circularpath = \pi{r}^{2}$
