(-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)

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 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)

5/4-7/6-(-2)/3=\ 3/4 (b) -3/4 (-7)/(12) (d) 7/(12)

Choose the correct option 5/4-7/6-(-2)/3=\ (a) 3/4 (b) -3/4 (c) (-7)/(12) (d) 7/(12)

sqrt(3+x)+sqrt(3-x)sqrt(3+x)-sqrt(3-x)(5)/(7)( b) (7)/(5)(c)(5)/(12) (d) (12)/(5)
