Question

anybody answer this question please​

Answer 1

2) (5/6)^3 x (6/5)^-8

==> (5/6)^3 x (5/6)^8

==> (5/6) ^3+8

==> 5/6^11

3) (50-20)x30

according to bodmas, first solve bracket.

30x30

==> 30^2

==> 900

Answer 2

$2) \: \: \: { ( \frac{5}{6} )}^{3} \times {(\frac{6}{5} )} ^{ - 8} \\ \\ = { (\frac{5}{6} )}^{3} \times {(\frac{5}{6})}^{8} \green{....using \: {(\frac{a}{b})}^{ - n}= {(\frac{b}{a})}^{ n}} \\ \\ = {( \frac{5}{6} )}^{3 + 8} \\ \\ =\boxed{{(\frac{5}{6} )}^{11}} \\ \\ \\ \\ 4) \: \: \: (50 - 20) \times 30 \\ \\ = 30 \times 30 \\ \\ = ( {30})^{2} \\ \\ = \boxed{900}$
