Answer 2

Step-by-step explanation:

(i)= 3V5 × 2V5

= 3×2×V5×V5

= 6×5

= 30

(ii)= 6V15×4V3

= 6×4×V3×V3×V5

= 24×3×V5

= 72V5

(iii)= 2/6×3/3

=1/3×1

=1/3

(iv)= 3V8×3V2

= 3×3×V2×V2×V2×V2

=9×2×2

=36

(v)= V10×V40

= V10×V10×V4

=10V4

(vi)= 3V28×2V7

= 3×2×V7×V7×V4

=(V4=V2×V2=2)

= 6×7×2

= 84
