Answer 1

\(a,4.3.12.6=2^2.3.2^2.3.2.3\)

                   \(=2^5.3^3.\)

\(b,27.81.3=3^3.3^4.3=3^8.\)

\(c,11.121.66.6=11.11^2.11.6.6\)

                           \(=11^4.6^2.\)

\(d,21.3.7.49=3.7.3.7.7^2\)

                      \(=3^2.7^4.\)

Answer 2

a, 4.3.12.6

= 2.2.3.2.2.3.3.2

= 2⁵.3³

b, 27.81.3

= 3.3.3.3.3.3.3.3

= 3⁸

c, 11.121.66.6

= 11.11.11.11.6.6

= 11⁴.6²

d, 21.3.7.49

= 3.7.3.7.7.7

= 3².7⁴

Answer 3

a. 4 . 3 . 12 . 6 = 12 . 12 . 6 = 12² . 6

b. 27 . 81 . 3 = 81 . 81 = 81²

c. 11 . 121 . 66 . 6 = 11 . 121 . 11 . 6 . 6 = 121 . 121 . 6 . 6 = 121² . 6²

d. 21 . 3 . 7 . 49 = 21 . 21 . 49 = 21² . 7²

Answer 4

a)4.3.12.6=2⁵.3³

b)27.81.3=3⁸

c)11.121.66.6=11⁴.6²

d)21.1.7.49=3².7⁴

Answer 5

\(d,3^2.7^4\)\(a,2^3.3.6^2\)

\(b,3^8\)

\(c,11^4.6^2\)

Answer 6

a) \(4.3.12.6=2^2.3.2^2.3.2.3=\left(2^2.2^2.2\right).\left(3.3.3\right)=2^5.3^3\)

b) \(27.81.3=3^3.3^4.3=3^8\)

c) \(11.121.66.6=11.11^2.11.6.6=\left(11.11^2.11\right).\left(6.6\right)=11^5.6^2\)

d) \(21.3.7.49=3.7.3.7.7^2=\left(3.3\right).\left(7.7.7^2\right)=3^2.7^4\)
