What is the expanded form of the expression ∑i=04i4? 04+14+24+34 14+24+34+44 02+42 04+14+24+34+44
dimulka [17.4K]

The expression is an illustration of the summation notation

The expanded form of the summation notation \sum\limits^{4}_{i = 0} i^4 is  0^4 + 1^4 + 2^4 + 3^4+4^4

<h3>How to determine the expanded form</h3>

The summation notation is given as:

\sum\limits^{4}_{i = 0} i^4

The above summation notation represents the sum of the numbers raise to the power of 4, from 0 to 4

So, we have:

\sum\limits^{4}_{i = 0} i^4 = 0^4 + 1^4 + 2^4 + 3^4+4^4

Hence, the expanded form of \sum\limits^{4}_{i = 0} i^4 is  0^4 + 1^4 + 2^4 + 3^4+4^4

The sun of three numbers is 98. If the ratio of the first to second is 2:3 and that of the second to the third is 5:8; then the
melisa1 [442]

Answer:

30

Step-by-step explanation:

solve the system of equations:

a+b+c=98,

a/b=2/3,

b/c=5/8

so

a + 3/2 a + 3/2 * 8/5 a = 98

49/10 a = 98

a = 980/49 = 20

then b = 3/2 * 20 = 30

(and c = 48)
