The correct option is D a=b
Let's calculate a and b:
a=1.1234×100
To multiply: Since there are two zeroes in 100, move the decimal point two places to the right in 1.1234
⇒a=112.34
b=0.11234×1000
To multiply: Since there are three zeroes in 1000, move the decimal point three places to the right in 0.11234
⇒b=112.34
∴a=b=112.34
