Check Mark

Answer to Problem 20A

The value of bd+e3 is 1.

Explanation of Solution

Given:

The value of b is 8, d is 4 and e is 2.

Calculation:

The algebraic expression is given below:

  bd+e3  ... (1)

Substitute 8 for b, 4 for d and 2 for e in equation (1) as follows:

  bd+e3=84+23=2+23=43=1

Thus, the value of bd+e3 is 1.

Conclusion:

The value of bd+e3 is 1.

To determine

(b)

The value of bd(3+4db).

Answer to Problem 20A

The value of bd(3+4db) is 352.

Explanation of Solution

Given:

The value of b is 8, d is 4 and e is 2.

Calculation:

The algebraic expression is given below:

  bd(3+4db)  ... (1)

Substitute 8 for b and 4 for d in equation (1) as follows:

  bd(3+4db)=8×4(3+4×48)=32(3+168)=32×11=352

Thus, the value of bd(3+4db) is 352.

Conclusion:

The value of bd(3+4db) is 352.

To determine

(c)

The value of 5b(bd+3).

Expert Solution

Answer to Problem 20A

The value of 5b(bd+3) is 5.

Explanation of Solution

Given:

The value of b is 8, d is 4 and e is 2.

Calculation:

The algebraic expression is given below:

  5b(bd+3)  ... (1)

Substitute 8 for b and 4 for d in equation (1) as follows:

  5b(bd+3)=5×8(8×4+3)=40(32+3)=4035=5

Thus, the value of 5b(bd+3) is 5.

Conclusion:

The value of 5b(bd+3) is 5.

To determine

(d)

The value of 3e(be)d(b2).

Expert Solution

Answer to Problem 20A

The value of 3e(be)d(b2) is 20.

Explanation of Solution

Given:

The value of b is 8, d is 4 and e is 2.

Calculation:

The algebraic expression is given below:

  3e(be)d(b2)  ... (1)

Substitute 8 for b, 4 for d and 2 for e in equation (1) as follows:

  3e(be)d(b2)=3×2(82)4×(82)=(6×6)(4×4)=3616=20

Thus, the value of 3e(be)d(b2) is 20.

Conclusion:

The value of 3e(be)d(b2) is 20.

To determine

(e)

The value of 12de[3b(d+e)+4].

Expert Solution
Check Mark

Answer to Problem 20A

The value of 12de[3b(d+e)+4] is 2.

Explanation of Solution

Given:

The value of b is 8, d is 4 and e is 2.

Calculation:

The algebraic expression is given below:

  12de[3b(d+e)+4]  ... (1)

Substitute 8 for b, 4 for d and 2 for e in equation (1) as follows:

  12de[3b(d+e)+4]=12×42[3×8(4+2)+4]=24[246+4]=2424+2=2

Thus, the value of 12de[3b(d+e)+4] is 2.

Conclusion:

The value of 12de[3b(d+e)+4] is 2.

To determine

(f)

The value of b+d+ede+bd2de3.

Expert Solution
Check Mark

Answer to Problem 20A

The value of b+d+ede+bd2de3 is 103.

Explanation of Solution

Given:

The value of b is 8, d is 4 and e is 2.

Calculation:

The algebraic expression is given below:

  b+d+ede+bd2de3  ... (1)

Substitute 8 for b, 4 for d and 2 for e in equation (1) as follows:

  b+d+ede+bd2de3=8+4+242+8(4)24(2)3=142+12832=7+96=103

Thus, the value of b+d+ede+bd2de3 is 103.

Conclusion:

The value of b+d+ede+bd2de3 is 103.
