Expert Solution

Answer to Problem 62E

  (4b)12(8b14)=32b34

Explanation of Solution

Given information:

Given expression

  (4b)12(8b14)

Calculation:

Consider the given expression.

  (4b)12(8b14)

Now, use the first law of exponents, which states

  aman=am+n

And combine like terms

  (4b)12(8b14)=48b12+14=32b2+14=32b34

Hence,

  (4b)12(8b14)=32b34

(b)

To determine

To evaluate: the given expression (3a34)(5a12) .

Expert Solution

Answer to Problem 62E

  (3a34)(5a12)=15a54 .

Explanation of Solution

Given information:

Given expression

  (3a34)(5a12) .

Calculation:

Consider the given expression.

  (3a34)(5a12)

Now, use the first law of exponents, which states

  aman=am+n

And combine like terms

  (3a34)(5a12)=35a34+12=15a3+24=15a54

Hence,

  (3a34)(5a12)=15a54
