(-12)^(3)+(7)^(3)+(5)^(3)

Express in exponential form. 1. (-4)^(5)-:c^(5) 2. (12)^(3)-:(-4)^(3) 3. (7^(18)-:7^(12))xx7^(8)

Evaluate : (iv) (3)/(8)+(-5)/(12)+(3)/(7)+(3)/(12)+(-5)/(8)+(-2)/(7)

The value of x for which ((7)/(12)) ^(-4) xx ((7)/(12))^(3x) = ((7)/(12))^(5) is

(1+(1)/(3)+(1)/(3)*(3)/(3)+(1)/(3)*(5)/(9)*(5)/(9)+(1)/(3)*(3)/(6)*(5)/(9)*(7)/(12)+)^(2)

{(7)/(5)xx((-3)/(12))}+{(7)/(5)xx(5)/(12)}

Verify the following: (i) (-12)/(5)+(2)/(7)=(2)/(7)+(-12)/(5) (ii) (-5)/(8)+(-9)/(13)= (-9)/(13)+(-5)/(8) (iii) 3+(-7)/(12)=(-7)/(12)+3 (iv) (2)/(-7)+(12)/(-35)=(12)/(-35)+(2)/(-7)

The smallest of the fractions (3)/(4), (5)/(6), (7)/(12), (2)/(3)
