Question

Match the expressions with their resultant terms in exponential form.

Options:

1. 13^7

2. 13^19

3. 13^1

4. 13^-22

5. 13^-14

6. 13^15

7. 13^-7

Answer 1

3; 4; 6; 1

Explanation:

The base is 13 in each of the product factors, so the exponent of the product is the sum of the exponents of the factors:

1. -11 +16 -3 +4 -5 = 1 . . . . matches option 3
2. -21 -4 -5 +14 -6 = -22 . . . . matches option 4
3. 33 -2 +5 -13 -8 = 15 . . . . matches option 6
4. 0 +10 -12 +5 +4 = 7 . . . . matches option 1
