Solve : `9^(8.6)xx8^(3.9)xx72^(4.4)xx9^(3.9)xx8^(8.6)=72^?`.

Solve :- 9 xx (8+3) ?

(2xx3)^3-:(4xx9)^2xx(27xx8)^2=6^?

Solve ((9.8)^(3)-(6.8)^(3))/(9.8^(2)+9.8xx6.8+6.8^(2))

9.2 xx 8.8 = 72.96

Solve ((5.9)^(3)+(1.8)^(3)+(4.8)^(3)-3xx5.9xx1.8xx4.8)/((5.9)^(2)+(1.8)^(2)+(4.8)^(2)-5.9xx1.8-1.8xx4.8-4.8xx5.9)

Simplify : (i) (12^(4)+9^(3)xx4)/(6^(3)xx8^(2)xx27)( ii) 2^(3)xx a^(3)xx5a^(4)

3sqrt((3^(6)xx4^(3)xx2^(6))/(8^(9)xx2^(3)) =____________

Solve : (3^(6)times y^(8))/(9^(2)times y^(3))

Simplify and write the answer in exponential form. a. (4^(3)xx10^(5))/(2^(3)xx5^(4)) b. ((6^(4))^(4)xx5^(8)xxa^(6))/(9^(9)xx10^(6)) c. (15^(32)xx12^(15)xx54^(4))/(25^(12)xx18^(8)xx9^(2)) d. (8^(4)xx6^(4))/(2^(8)xx3^(3)) e. (8^(12)xx(9^(2))^(5)xx5^(6))/(6^(9)xx15^(4)) f. (21^(16)xx70^(8)xx36^(15))/(49^(4)xx15^(5)xx24^(6))
