`{(5 ^2+(12^2)^(1/2))}^3`

Evaluate the following : {(5^(2)+12^(2))^(1)}^(3)( ii) {(6^(2)+8^(2))^(1)}^(3)

Find the value of (2.3a^(5)b^(2)) xx(1.2 a^(2)b^(2)) when a = 1 and b = 0.5

The value of (12^(2) + 5^(2))^(1//2) is

(5 1/4-3 1/3)= (12)/(23) (b) 2 1(11)/(12) (d) (11)/(12)

(i) (1.2)^3 (ii) (3.5)^3

The series expansion of log_(e) [(1 + x^((1 + x))(1-x)^(1-x)] is (1) 2[(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (2) [(x^(2))/(1.2) + (x^(4))/(3.4)+(x^(6))/(5.6)+...] (3) 2[(x^(2))/(1.2) + (x^(4))/(2.3)+(x^(6))/(3.4)+...] (4) 2[(x^(2))/(1.2) -(x^(4))/(2.3)+(x^(6))/(3.4)-...]

Simplify (1. 5p + 1.2 q) ^(2) - (1. 5p - 1.2 q) ^(2)

Prove that (i) " 2sin " (5pi)/(12) " sin " (pi)/(12)=(1)/(2) (ii) " 2 cos " (5pi)/(12) " cos " .(pi)/(12)=(1)/(2) (iii) " 2 sin ".(5pi)/(12) " cos " (pi)/(2) = ((2+sqrt(3))/(2))
