Answer to Problem 22A

The value of m+mp2r2 is 76.

Explanation of Solution

Given:

The value of m is 5, p is 4 and r is 3.

Calculation:

The algebraic expression is given below:

  m+mp2r2  ... (1)

Substitute 5 for m, 4 for p and 3 for r in equation (1) as follows:

  m+mp2r2=5+(5×42)32=5+809=859=76

Thus, the value of m+mp2r2 is 76.

Conclusion:

The value of m+mp2r2 is 76.

Answer to Problem 22A

The value of (p+2)2(mr)2 is 144.

Explanation of Solution

Given:

The value of m is 5, p is 4 and r is 3.

Calculation:

The algebraic expression is given below:

  (p+2)2(mr)2  ... (1)

Substitute 5 for m, 4 for p and 3 for r in equation (1) as follows:

  (p+2)2(mr)2=(4+2)2×(53)2=(6)2×(2)2=36×4=144

Thus, the value of (p+2)2(mr)2 is 144.

Conclusion:

The value of (p+2)2(mr)2 is 144.

Answer to Problem 22A

The value of ( pr)22pr+m3 is 185.

Explanation of Solution

Given:

The value of m is 5, p is 4 and r is 3.

Calculation:

The algebraic expression is given below:

  ( pr)22pr+m3  ... (1)

Substitute 5 for m, 4 for p and 3 for r in equation (1) as follows:

   ( pr )22pr+m3= ( 4×3 )22(4×3)+53=144212+125=72+113=185

Thus, the value of ( pr)22pr+m3 is 185.

Conclusion:

The value of ( pr)22pr+m3 is 185.

Answer to Problem 22A

The value of p3+3p12m2+15 is 1.5.

Explanation of Solution

Given:

The value of m is 5, p is 4 and r is 3.

Calculation:

The algebraic expression is given below:

  p3+3p12m2+15  ... (1)

Substitute 5 for m and 4 for p in equation (1) as follows:

  p3+3p12m2+15=43+3×41252+15=64+121225+15=6440=1.6

Thus, the value of p3+3p12m2+15 is 1.5.

Conclusion:

The value of p3+3p12m2+15 is 1.5.

Answer to Problem 22A

The value of r33p9+m2(mp6r)2 is 109.

Explanation of Solution

Given:

The value of m is 5, p is 4 and r is 3.

Calculation:

The algebraic expression is given below:

  r33p9+m2(mp6r)2  ... (1)

Substitute 5 for m, 4 for p and 3 for r in equation (1) as follows:

  r33p9+m2(mp6r)2=333×49+52(5×46×3)2=273+25(2)2=9+100=109

Thus, the value of r33p9+m2(mp6r)2 is 109.

Conclusion:

The value of r33p9+m2(mp6r)2 is 109.

To determine

(f)

Answer to Problem 22A

The value of m3p2+5r2+p+2mm+p+r is 13.83.

Explanation of Solution

Given:

The value of m is 5, p is 4 and r is 3.

Calculation:

The algebraic expression is given below:

  m3p2+5r2+p+2mm+p+r  ... (1)

Substitute 5 for m, 4 for p and 3 for r in equation (1) as follows:

  m3p2+5r2+p+2mm+p+r=5342+532+4+2×55+4+3=12516+59+1412=1449+1412=456+4236

Simplify the above equation as follows:

  m3p2+5r2+p+2mm+p+r=456+4236=49836=13.83

Thus, the value of m3p2+5r2+p+2mm+p+r is 13.83.

Conclusion:

The value of m3p2+5r2+p+2mm+p+r is 13.83.
