Question

If 3676.48 can be written in expanded form as:
$3\times {10}^a+b\times {10}^2+7\times {10}^c+6\times {10}^0+4\times {10}^d+e\times {10}^{-2}$ .
$\text{Find the value of}a+b-c-d-e.$

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A 1

3676.48 can be written in expanded form as:
$3\times {10}^3+6\times {10}^2+7\times {10}^1+6\times {10}^0+4\times {10}^{-1}+8\times {10}^{-2}$.
a= 3, b=6, c=1, d= -1, e=8

a + b -c -d-e = 3 + 6 -1 +1 -8 =1
