Question

20. Simplify each of the following:

(i) 5√16 x 5√2
(ii)4√243/4√3

(ii) (3 +√2)(4+√7) (iv) (√3- √2)^2​

Answer 1

Step-by-step explanation:

1 - 5√16 × 5√2

= 5 × 5 × √16 x √2

= 25 × 4 × √2

= 100√2

= 100 × 1.414

= 141.4

2 - 4√243/4√3

= 4√243

4√3

= 243^¼ = (3)⁵×^¼ = (3)⁵/⁴ ‐ ¹/⁴ = (3)⁴/⁴ = 3¹

3^¼ (3)^¼

= 3
