Question

5. Simplify:
i. 2x10³.
ii. 7²x 2².
iii. 2³x 5
iv. 3x 4⁴.
v. 0 x10².
vi. 5² x 3³.
vii. 2⁴x 3².
viii. 3² x 10 ⁴​

Answer 1

Step-by-step explanation:

(i)→2×(10³)

→2000

(ii)→(7²)×(2²)

→196

(iii)→(2^3)x-5=1/16

→(2^3)x=1/16+5

     →1/16+80/16

     →x=81/(16*8)

    →0.6328125

•°•substituting the value of x in the second equation

we get,

→23x+1=(23*0.6328125)+1

          →15.5546875
