2 to the third power is 2³
so 2 to the third power times -5 is 2³ * (-5)
which on simplification will be 8* (-5) =-40
Answer:
A number is 157,355
Step-by-step explanation:
We are given a six digit number 156,350. If we subtract 156,350 from a unknown number (x) rsult should be 4 digit number.
Let we suppose 4-digit number smallest as well largest
Smallest 4-digit number = 1000
If we subtract 156,350 from x to get 1000
x-156350=1000
x=156350+1000
x=157,350
Largest 4-digit number = 9999
If we subtract 156,350 from x to get 9999
x-156350=9999
x=156350+9999
x=166,349
Four digit number should be lie between 157,350 to 166,349
We can choose any number between them
Thus, 157,355 is a number to get 4-digit number when 156,350 is subtract.

Step-by-step explanation:
Answer:
x=2,3
Step-by-step explanation:
(x- 2) (x - 3) =0
Using the zero product property
x-2 =0 x-3 =0
x-2+2=0+2 x-3+3 =0+3
x=2 x+3
