Ans no. 42
x=5
therefore y=3x
3 *5 times
3*3*3*3*3=153. (here star means multiplication)
y=x cubic 3
therefore...
5*5*5=125
y=3x (part one) is greater...
Answer no. 43
2x
x=10
2*2*2*2*2*2*2*2*
2*2=1024
100xsquare
therefore...
100*10*10=10000
100xsquare (part 2 is bigger.)
Answer no. 41
x=7
(part 1)
10*2*2*2*2*2*2*2=1280
part2
200*7*7=9800
therefore part 2 is greater
Answer no. 40
y=4x
x=2
part 1
4*4=16
part 2
2*2*2*2=16
therefore both are same....
HOPE THIS ANSWER WILL HELP YOU!!!
GOOD LUCK
