Answer:
a. 2*-2*3=-12
b. -2*3*5 = -30
c. (-2)^2+2*5= 14
d. 2*-2+3*3-5*5= -20
e. -2(3-5) = 4
f. 3*5-(-2)*5+(-2)*3 = 19

4 x 10^-7 (7 x 10^-9) (1 x 10^4) (2 x 10^4)
Answer:
rearrange them properly to get
x-y=7
-3x+y=12
( by elimination method)
x-y = 7
-3x+y=
(x+ –3x) + (–y+y) = (7+12)
-2x+0= 19
x= -9.5
from eqn(i)
x-y=7
-9.5 - y=7
-y=16.5
y= -16.5
