Evaluate: `(2a+3b+5)(2a-3b+5)`

Evaluate : (iii) (4a - 3b) (2a + 5b)

Evaluate : a. ((3)/(5))^(3) b. ((-2)/(7))^(2)

Evaluate : 5a^(3)b^(2) when a =3 and b = -2

a^2b^3\ X\ 2a b^2 is equal to: (a) 2a^3b^4 (b) 2a^3b^5 (c) 2a b (d) a^3b^5

Evaluate AB={:[(3,-1),(3,5),(-2,1)]:}{:[(1,-2),(5,-3)]:} . A is 3 by 2, and B is 2 by 2.

If a^(2)+b^(2)+c^(2)=1 where, a,b, cin R , then the maximum value of (4a-3b)^(2) + (5b-4c)^(2)+(3c-5a)^(2) is

Expand |(2a , 3b), (5a , 7a)|

Subtract: 2a-b from 3a-5b

If a : b=2:5, . find the value of (3a+2b)/(4a+b)

Evaluate : and write the answer in factors form : (3a- 2b)^(3) + (2b- 5c)^(3) + (5c- 3a) ^(3)
