1(a) no idea !
1(b) ans = 9
i.e. the formula of laws of indices is used . Where, the base are same so the powers get subtracted while changing the division sign. But in this case the sign of 5 is minus so it becomes plus -4-(-5) and finally -4+5= 1 .
(c) the diagonals of parallelogram are parallel and equal to each other .
(d)
A=a+b/2 * h
(f) √18 = √2*3*3
=3 √2
2.
(a) T
(b) F
(c) F
(d)F ( I’m not sure)
