Answer 1

${2}^{4} \div {4}^{2} = 16 \div 16 = 1 \\ {2}^{3} \times {5}^{3} = 8 \times 125 = 1000 \\ {5}^{2} \times {2}^{4} = 25 \times 16 = 400 \\ {7}^{2} \div {5}^{0} = 49 \times 1 = 49 \\ {18}^{2} \div {3}^{4} = 324 \div 81 = 4$

Answer 2

2⁴ : 4² = 16 : 16 = 1

2³ x 5³ = ( 2 x 5 )³ = 10³ = 1 000

5² x 2⁴ = 5² x ( 2² )² = ( 5 x 4 )² = 20² = 400

7² : 5⁰ = (7 x 7 ) : 1 = 49 : 1 = 49

18² : 3⁴ = ( 2 x 9 )² : 3⁴ = 2² x 3⁴ : 3⁴ = 2² = 4
