Answer:
3.4*10^1159
Step-by-step explanation:
2,000,000 x 10,000 x 170 x 10E1146
2,000,000 x 10,000 = 2*10^10
2*10^10*170 =340*10^10
Putting this in proper scientific notation by moving the decimal 2 places to the left, means adding 2 to the exponent
3.4*10 ^ (10+2)
3.4*10^12
10E 1146 means 10*10^1146
This is really 1 * 10^(1146+1)
3.4*10^12 * 10^1147
We add the exponents
3.4*10^(12+1147)
3.4*10^1159
15-32= 32-15= 32 -15 15 -32
<h2>727</h2>
Step-by-step explanation:
Let us denote the three digit number by 
, where 
is the hundreds digit, 
is the tens digit and 
is the ones digit.
Hundreds digit = = Ones digit =
Sum of digits = 
So, 
On exchanging tens and ones digit, value increases by 45. So 
is 45 greater than .
∴ Required number is 727
