Q10

a) 2^(-1) = 1/2

a) 2^(-1) = 1/2b) 2^(-3) = 1/2^3

a) 2^(-1) = 1/2b) 2^(-3) = 1/2^3 = 1/8

a) 2^(-1) = 1/2b) 2^(-3) = 1/2^3 = 1/8c) 2^(-2) = 1/2^2

a) 2^(-1) = 1/2b) 2^(-3) = 1/2^3 = 1/8c) 2^(-2) = 1/2^2 = 1/4

a) 2^(-1) = 1/2b) 2^(-3) = 1/2^3 = 1/8c) 2^(-2) = 1/2^2 = 1/4Q11

a) 3^(-2) = 1/ 3^2

a) 3^(-2) = 1/ 3^2 = 1/ 9

a) 3^(-2) = 1/ 3^2 = 1/ 9b) 2^(-3) = 1/ 2^3

a) 3^(-2) = 1/ 3^2 = 1/ 9b) 2^(-3) = 1/ 2^3 = 1/8

a) 3^(-2) = 1/ 3^2 = 1/ 9b) 2^(-3) = 1/ 2^3 = 1/8c) 6^(-1) = 1/6

a) 3^(-2) = 1/ 3^2 = 1/ 9b) 2^(-3) = 1/ 2^3 = 1/8c) 6^(-1) = 1/6Q12

a) 2^2 + 2^0 + 2^(-2) = 4 + 1 + 1/4

a) 2^2 + 2^0 + 2^(-2) = 4 + 1 + 1/4 =21/4

a) 2^2 + 2^0 + 2^(-2) = 4 + 1 + 1/4 =21/4b) 10^(-1) + 10^0 + 10^3 = 1/10 + 1 +1000

a) 2^2 + 2^0 + 2^(-2) = 4 + 1 + 1/4 =21/4b) 10^(-1) + 10^0 + 10^3 = 1/10 + 1 +1000 = 1001.1

a) 2^2 + 2^0 + 2^(-2) = 4 + 1 + 1/4 =21/4b) 10^(-1) + 10^0 + 10^3 = 1/10 + 1 +1000 = 1001.1Q13

a) 100 =10^2

a) 100 =10^2b) 1000 = 10^3

a) 100 =10^2b) 1000 = 10^3Q14

a) 9^2 x 9^3 = 9^(2+3)

a) 9^2 x 9^3 = 9^(2+3) = 9^5

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049b) 8 x 8^2 = 8^(1+3)

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049b) 8 x 8^2 = 8^(1+3) = 8^4

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049b) 8 x 8^2 = 8^(1+3) = 8^4 = 512

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049b) 8 x 8^2 = 8^(1+3) = 8^4 = 512c) 7^5 ÷ 7^2 = 7^(5-2)

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049b) 8 x 8^2 = 8^(1+3) = 8^4 = 512c) 7^5 ÷ 7^2 = 7^(5-2) = 7^3

a) 9^2 x 9^3 = 9^(2+3) = 9^5 = 59049b) 8 x 8^2 = 8^(1+3) = 8^4 = 512c) 7^5 ÷ 7^2 = 7^(5-2) = 7^3 = 343
