Write in simplified form :

`2^9 times 3^5 times 5^4 times 7^6`

Evaluate : 5/2 times 7/4 times 9/6 times 2/3

Evaluate : 7/9 times 4/5 times 3/2

(v) Simplify: (-7/9) times 3/8 times (-4/7)

Evaluate : ( -2/3 )^7 times ( -3/5 )^6 times ( 5/6 )^5 times ( 1/3 )^-7

Evaluate : 9/7 times 5/3 ÷ 5/2 times 9/2 + 7/3

Solve : 5/9 times 6/3 + 4/5 times 6/3 - 1/2 times 4/8 + 1/2

Evaluate : 2/5 times 3/7 - 1/6 times 3/2 + 1/4 times 2/5 =

Evaluate : 5/6 times 3/2 + 3/2 times 4/6 = 7/5 times 3/5 + x

Expand the exponents : 1. a^5 = a times a times a times a times a 2. 3^6 = ------ 3. 5^5 = ------ 4. r^7 = ------ 5. 2^m = ------

Evaluate : ( 5/7 )^3 times ( 5/7 )^-6 times ( 1/3 )^-2 times ( 3/5 )^-2
