Answer 1

Answer:

3.i)7590087=7.590087×10^6

ii)508000000=5•08000000×10^8

III)41300000=4•1300000×10^7

4) 16 x 8 x 43 =5,504

5) (49 x 38x 512)/(642 x 253 x 272)=

(49×38×16)/(321×253×16)=29,792/1,380,621

6) 5 x 125 x 625 x 15625=5×5^3×5^4×5^6

7)

8)(-7)^3=-7×-7×-7=-343

9)(2/3)^9 x (4/9)^-6 =(2/3)^9×(4/9)^-indic2/3)^9×(4/3)^-6+1

=(2/3)^9×(4/3)^-5( according to the lawof indices )
