Answer:
1. 49.02 = 40 + 9 + 0.0 + 0.02
2.[tex]49.02 = 4 \times (10)^1 + 9 \times (10)^0 +0 \times (10^{-1} + 2 \times (10)^{-2}[/tex]
Step-by-step explanation:
Part : 1
To write 49.02 as EXPANDED FORM
Now, by place value chart, we know
Ten Th. , Thousand, Hundreds, Tens , units DECIMAL, Tenth, Hundredth
Putting the value of decimal just below decimal ,we get:
Place value of 4 = 4 tens = 4 x 10 = 40
Place value of 9 = 9 ones = 9 x 1 = 9
Place value of 0 = 0 tenth = 0 / 10 = 0
Place value of 2 = 2 hundredth = 2 / 100 = 0.02
⇒ 49.02 = 40 + 9 + 0.0 + 0.02
Part : 2
Now, rewriting terms using powers of 10, we get:
40 = 4 x 10 = 4 x [tex](10)^1[/tex]
9 = 9 x [tex](10)^0[/tex]
0 = 0 x [tex](10)^{-1}[/tex]
0.02 = 2 x [tex](10)^{-2}[/tex]
⇒[tex]49.02 = 4 \times (10)^1 + 9 \times (10)^0 +0 \times (10^{-1} + 2 \times (10)^{-2}[/tex]
